🤓 น้องๆ รู้ไหมครับว่า computer vision
อ่านว่า "คอมพิวเตอร์วิชั่น"
เป็นศาสตร์ทางคอมชั้นสูงอีกแขนงหนึ่ง
ที่ทำให้คอมพิวเตอร์มองเห็นได้ดุจดังตามนุษย์
เป็นไงฟังแล้วเท่ห์มั๊ยละ
.
ปกติมนุษย์เวลาเห็นวัตถุ สิ่งของ สิ่งมีชีวิต อยู่ในรูป หรือในวีดีโอ
เช่น เห็นปูุ๊บก็จะบอกได้ทันทีว่า
ในรูปหรือวีดีโอมีหมา แมว แก้วน้ำ แจกัน ฯลฯ
เรื่องแบบนี้สำหรับคน ถือว่าโคตรรรรรรรรรง่ายๆ
.
แต่ทว่าในมุมของคอมพิวเตอร์
มันยากมากกกกกกกกกกกกกก
.
ถ้าคอมมันทำได้ก็ถือว่าฉลาดมากแล้ว
ถือว่า intelligent เป็นสิ่งอัจฉริยะในมุมของคอม
ซึ่งการแยกแยะว่าสิ่งที่อยู่ในรูปว่ามันเป็นอะไร
ภาษาอังกฤษเรียกว่า classification (แยกแยะประเภท)
.
สำหรับศาสตร์ computer vision 💻 💻
มันแตกแขนงได้หลายเทคนิค หลายสาย
แต่ในโพสต์นี้จะพูดถึงเฉพาะแค่ 2 เรื่อง เท่านั้นได้แก่
.
☑ 1) การทำ Object detection
เป็นการตรวจจจับวัตถุในรูป
ในมุมการ classification มันแค่บอกว่าสิ่งในรูปคืออะไร
แต่ Object detection จะไม่ใช่แค่บอกว่าสิ่งที่อยู่ในรูปคืออะไรเท่านั้น
.
😲 😲 มันเหมือนอัพเกรตจากความสามารถ classification
เพื่อพัฒนาไปตีกล่องสี่เหลี่ยมล้อมรอบ (ภาษาอังกฤษเรียกว่า Box)
ตีกล่องเพื่อบอกตำแหน่งสิ่งที่มันตรวจจับในรูปหรือในวีดีโอได้ ...โอ้วแม่เจ้าจะเทพไปถึงไหน
.
.
☑ 2) การทำ Segmentation
จะแอดวานซ์จาก Object detection
เหมือนเป็นเวอร์ชั่นอัพเกรตอีกต่อหนึ่ง
.
คือมันไม่ได้ตีกรอบล้อมรอบวัตถุนะ
แต่มันจะยิ่งกว่านั้น
...ก็คือมันจะไฮไลท์ (ฝรั่งบอกว่า mask)
....มันจะระบุพื้นที่วัตถุ สิ่งของ ที่มันตรวจจับได้ (เหมือนเราแรงงานไปยังวัตถุนั้น ๆ)
.
.
ซึ่งศาสตร์ computer vision ปัจจุบันนี้
นิยมเอา AI (ปัญญาประดิษฐ์) มาใช้งาน
จริงมันก็ทำอย่างอื่นได้นอกจากสองเรื่องที่ผ่าน เช่น
pose estimation ตรวจจับจุดต่างๆ ของมนุษย์ แบบกล่องสองผี 💀💀 💀 ....จนปรึ้นๆๆ น่ากลัวหรือเปล่า เป็นต้น
.
และมีข่าวดีสำหรับใครที่สนใจเขียนโปรแกรม 👏 👏
สำหรับงาน Object Detection กับ Segmentaion
ผมทำตัวอย่างการใช้งานไว้แล้ว
มี 5 แบบ ลองเข้าไปดูโค้ดได้ที่นี้

🤓 Do you know that computer vision?
Read ′′ Computer Vision ′′
It's another elite computer science.
That makes computers visible as human eyes.
How are you? Are you cool?
.
Normally humans see objects of living things in the photo or video.
Such as seeing a crab, I can tell you right away.
In the picture or video, there are dogs, cats, mug, vase etc.
This kind of thing for people is considered simple.
.
But in the corner of computer
It's very difficult.
.
If a computer can do it, it's very clever.
Intelligent is considered genius in the corner of the computer.
Which digest what's in the picture is what it is.
English is called classification (type digest)
.
For computer vision science 💻 💻
It's broken. Many tricks. Many lines.
But in this post, it's only about 2 stories.
.
☑ 1) Object detection
Detection of the objects in the photo
In classification angle, it just says what is in the picture.
But Object detection won't just say what's in the picture.
.
😲 😲 It's like an upgrade from ability classification.
To develop, hit a square box, surround (English is called Box).
Hit the box to spot what it detects in the photo or video... Oh my god how can it be?
.
.
☑ 2) Making Segmentation
Will admin from Object detection
It's like another upgrade version.
.
Well, it doesn't hit the frame surrounding the object.
But it will be more than that.
... Well, it's going to be highlighted (Foreigner says mask)
.... It will identify the areas, objects, things that they detect (like we labor to that object).
.
.
The science of computer vision nowadays.
Popular to use AI (Artificial Intelligence)
True, it can do anything else but two things that pass, e.g.
pose estimation detects different points of human in two ghost box. 💀💀 💀 💀 💀.... so bad, scary, etc.
.
And some good news for anyone who is interested in programming 👏 👏
For Object Detection with Segmentaion
I made an example of use.
There are 5 designs. Check out the code here.
.
🔥 1. Imageai library work. Detection of objects in the photo.
https://colab.research.google.com/drive/1uQnZfPlRhplvcZKWiXn1jeytJIFEVLkV
🔥 2. usage of pixellib libraries. Detect objects in the photo.
https://colab.research.google.com/drive/1llWzReE3rS9wDfSGGm8M7RQ25jeEfSIi
🔥 3. uses of Tensorflow's Tensorflow library. A sample of Google detects objects in the photo.
https://colab.research.google.com/drive/12K-4uQ1tAvOukLb1-lwXx4bnXkeQupTk
🔥 4. Facebook's Detectron2 Library Uses rūp Objects Detector
https://colab.research.google.com/drive/1jnWFADFdZHz1LSyfXVKHY3fIwuY5F_uo
🔥 5 examples of using Msk RCN model. Detect objects in the photo.
https://colab.research.google.com/drive/1JGRIMQ1YSdMXkEZdC6QNGbI722tEQJTE
.
Ps. There are only code python because I need to get over it.
Because of this side job, this language is number one in AI event. At this time, I'm
(Can go to read textbooks. 1-2-3 python content in the textbook)
.
.
+++++ Public relations (selling items)

//反送中運動發展至今,國際輿論確是面臨挑戰,感謝眾志戰友敖卓軒 (Jeffrey Ngo)幫忙協作,我的Twitter剛發了 29 個 Tweet,嘗試爭取國際社會理解昨日立法會行動的來龍去脈。
不求國際社會的朋友完全同意昨日的所有舉措,但求理解前線戰友的意志,對他們有著多一分體諒,少一分責難。
行動過後,保持輿論支持仍是關鍵所在,需要具名拋頭露面的輿論工作,我們會好好努力,對比起你們所作的決志,我怎敢怠慢。

1. THREAD: Dear world, I want to say a few words about what happened in #HongKong yesterday.
2. An estimated 550,000 Hong Kongers made yesterday's annual July 1 protest the highest ever in turnout. It marked 22nd anniversary of the 1997 Hong Kong handover to China, now only 28 years before 'One Country, Two Systems' is set to expire due to the '50-year no change' policy.
3. Simultaneously as the peaceful demonstrations were taking place, other young protesters attempted to enter the Legislative Council complex. To understand WHY it happened, we must examine what happened over the past month.
4. Hong Kongers' strong resistance against proposed extradition arrangements with China was heard loud and clear around the world. Solidarity rallies took place in over 30 cities, and the international community spoke up.
5. We tried EVERYTHING available to us. On June 9, one million Hong Kongers took to the streets peacefully. But before the night had even ended, Chief Executive Carrie Lam released a statement saying she would press ahead with the bill in three days.
6. That’s why, in the morning of June 12, when the Legislative Council debate was set to take place, Hong Kongers were bracing for our last fight. We knew there would be no turning back. Beijing had enough votes because only 40 out of 70 seats are directly elected by the people.
7. And then there was miracle. Protesters managed to blockade the complex completely. Well-documented evidence published by the international media show excessive force used by the police. Many injuries ensued, but in any case lawmakers could not convene.
8. It was only after this escalation that Lam made a small compromise to pause the bill’s reading. Even she acknowledged events on June 12, NOT June 9, that changed her mind. Months of Hong Kongers and the world expressing concern did not matter to her at all until she saw blood.
9. But Lam called protesters ‘rioters’. She would not agree to an independent investigation on police brutality. She stopped short of withdrawing the bill, let alone stepping down. Combined with the first death of a protester, TWO MILLION people marched on June 16.
10. Hong Kong has 7.5 million people, so an equivalent of ONE IN FOUR out of the entire population protested in a single occasion. I am not aware of anything comparable to this level of discontent against a government in modern history.
11. Lam finally apologized two days later, but for what? For failing to ‘properly communicate’ to Hong Kongers what the extradition bill was all about. Even up until that point, then, the subtext was that she was still right and we were too stupid.
12. Commentators around the world thought the movement was over by then, because the bill had supposedly been ‘suspended’ and Lam had said sorry. But actually none of our demands were met. Lam refused dialogue with opposition lawmakers and continued to praise the police.
13. Since my release on June 17 from prison, I took part in a number of smaller-scale rallies, sit-ins and occasional skirmishes. We wanted to let Beijing and the world know the fight was far from over. The G-20 summit in Osaka was then fast approaching.
14. Hong Kongers’ determination was on full display again when, within 11 hours, we crowdfunded over HK$6.7 million for newspaper ads ahead of the G-20 summit calling for the world not to neglect us.
15. We were grateful for world leaders, including Prime Minister Abe Shinzo and President Donald Trump, for raising the issue of Hong Kong human rights in their respective meetings with Xi Jinping. Yet by June 29, our demands were still ignored. It appeared we were really losing.
16. Devastating news followed. Two additional young fellow protesters jumped to their deaths over this past weekend. The Hong Kong government was pushing us to the point of despair and desperation. We tried every possible way imaginable to make our voices heard.
17. In a democracy, this extradition bill would long ago have been terminated. Polls consistently show some 70% of Hong Kongers in favor of a full withdrawal. The political career of any other leader would also have been over with this level of resistance over such a long period.
18. Alas, Hong Kong is not a democracy. Lam, a puppet of Beijing is also unlike any leader. The source of her power comes not from Hong Kongers but from the Chinese Communist Party. This brings me back to events yesterday.
--------------
19. The protesters who broke into the Legislative Council complex were NOT rioters. They were NOT violent. Their objective was never to harm any individual. They wanted to make the regime hear Hong Kongers’ voice, and they had no other option. WE ALREADY TRIED EVERYTHING ELSE.
20. Perhaps not all of you will agree with every single action they took yesterday. But what are a few pieces of glass worth in comparison to the deaths of three young men and women? What are a few portraits worth in comparison to the very survival of Hong Kong as a place?
21. The moment they stepped into the building, they knew what awaited them. They would face almost certain prosecution and probable imprisonment over rioting charges, which carry a maximum sentence of 10 years. They have a whole life ahead of them.
22. Some well-intentioned opposition lawmakers tried to persuade protesters out of it. But they replied that since others had already perished, whatever physical and legal consequences they would face immediately paled in comparison. Watching this exchange put tears in my eyes.
23. Even after the break-in, protesters behaved with unimaginable discipline. They left cash at the counter before taking drinks from the cafeteria. They sealed the library off to preserve historical documents stored inside. Not a second did they lose their cool.
24. What kind of young people does Hong Kong produce? Smart, efficient, attentive and freedom-loving. I am proud of them, although I confess I do not have the courage to do what they did yesterday. I have been jailed three times, so I know full well what now lies ahead of them.
--------------
25. Sometimes in life we are forced to make split-second decisions that will forever alter us as individuals, and perhaps even alter the course of history. It is of course too soon to tell, but I can only hope that years later when we look back to 2019, we will have no regrets.
26. Hong Kongers remain as united as we ever are. I am proud of what our friends did last night. For the first time I was also tear gassed, right outside the complex when cops tried to clear our defense line. Moving forward, we will continue find our own place and fight on.
27. The ongoing protests have already defied the expectations of not just every commentator and scholar but also myself as an activist. I would be foolish to try to predict what is next.
28. If there is just one takeaway for the world: Events in Hong Kong are about so much more than the bill, more than Lam, more even than democracy. They all matter of course. But in the end it is about the future of Hong Kong beyond 2047, a future that belongs to our generation.
29. Please continue to keep an eye on us, and keep supporting us. On behalf of Hong Kongers I thank everyone for taking the time to learn about this unique place we call home. THREAD ENDS//

決定轉貼這篇文章,除了重申「言論自由」的重要,也提到Assange 必須主動面對性侵案件,對「身體自主」的尊重,以及與俄國過從甚密而帶來人權侵害的另一個隱憂。
是目前針對聲援Assange 所有聲明中,闡述最全面對的一篇文章。
【20190503聲援Assange記者會】
綠黨作為全球串連的政黨,對於國際人權的聲援,也責無旁貸。今(5/3)本黨代表出席聲援朱利安·亞桑傑(Julian P. Assange)的記者會,是基於 #資訊公開 跟 #新聞自由 的基本人權之故。
誠如大家所知,Assange是 #維基解密 的發起人跟代言人。這個網站,因為揭露了美國政府在戰爭中的不法情事,致使被美國政府通緝,日前在英國被捕,正在引渡回美國受審。
維基解密至今發佈了超過1000萬份文件、及相關分析,主要內容是涉及政府在戰爭、諜報,跟相關的官方機密文件的大型資料庫。Assange在訪談時表示:維基解密是全球最受嚴密監控的文件之大型資料庫。台灣綠黨一致肯認這件事情的意義,並且站在新聞自由的立場,呼籲政府應該接受人民的監督,以及面對自己的作為。
維基解密過去曾發布大量的敏感性資料,這些事情雖然令相關單位感到不堪或尷尬,但是這也促進了世界各國對人權的保障;包括2008年的《經濟學人》雜誌和國際特赦組織... 等,都多有肯定。《紐約每日新聞報》甚至將其列為「徹底改變新聞界的網站」中的第一名;這都是肯定維基解密對資訊揭露、促進世界和平的重大貢獻。
本黨認為:公權力需要受到監督、以及政府決策過程需要透明化的立場,在此進行聲援。無論是英國或美國,都是民主典範的國家,我們也在此呼籲,面對新興的網路科技資訊應用,兩國都該有其表率風範,落實對言論自由或新聞自由的保障。
我們同時也希望 Assange 先生,需要主動面對他在瑞典受指控的性侵害案;新聞自由誠然有其正當性,但是對於「身體自主權」的尊重,也是全球綠人的核心價值。
於此同時,維基解密網站的內容,近幾年也因為跟俄國過從甚密,而帶來人權侵害的另一隱憂。「資訊公開」如何避免成為極權主義介入他國內政的工具,這是當代資訊科技愈發普及之時,公民們也需要有對應的媒體識讀能力,才能營造出更為長遠的和平願景。
今天的記者會,是由本黨前召集人艾琳達協同召開。我們很榮幸可以在全球綠人的核心理念之下,關切此一國際人權事件,並對此發聲。美國跟澳洲的綠黨夥伴們,也都有相關的聲援行動。未來希望大家持續關注,無論是維基解密的相關進展、抑或是國內的假新聞濫竽充數,都能化阻力為助力,一起為了更好的台灣而努力!
其他各國綠黨對Julian Assange的聲援說明:

〔May 3, 2019, Press Conference - In Support of Julian Assange〕
As an international party, Green Party Taiwan is firm on its position to advocate international human rights. Therefore, in today’s press conference (5/3/2019), we gather here to support Julian P. Assange and to support human rights in forms of information transparency and freedom of the press.
Julian Assange is the founder and the spokesperson of Wikileaks, a website that uncovered and published unlawful engagements of the US army in 2010, and Assange was later indicted by the US government for it. Last month, Assange was arrested by the UK police and is now in the process of being extradited to the US for his trials.
Since its launch, WikiLeaks has published over 10 million entries of data and analysis, specializing in war, spy, corruption, and relevant official confidential documents. Assange has said in an interview that “WikiLeaks is a giant library of the world's most persecuted documents.”
Green Pary Taiwan believes it is essential that freedom of the press is protected and the governments are held accountable for their actions.
Wikileaks has published a large amount of sensitive information that embarrassed the authorities involved, but in the process, it helps promote the protection of human rights across the globe. Their endeavors were recognized by The Economist and Amnesty International, among others. New York Daily News even listed Wikileaks as one of the five “pioneering Web sites that could totally change the news.” These awards and recognitions highlight how much Wikileaks has contributed to increasing information transparency and world peace.
Green Party Taiwan believes that the public power needs to be overseen and that the making of public policies should be transparent. That is why we are here today to support Julian Assange. As the UK and the US are role models of democracy, we hope that both countries will lead by example and take actions in protecting freedom of speech and freedom of the press.
Meanwhile, we ask that Mr. Julian Assange take initiatives in facing the rape charges against him in Sweden. While the Green Party values freedom of speech, we also value each person’s boldly autonomy.
We also hope that Wikileaks will keep its distance from Russia, as it has been accused of assisting Russia in interfering with other countries‘ internal affairs, posting threats to human rights by empowering an authoritarian regime. How to protect “information transparency” from becoming a tool of authoritarian interference is an urgent issue that needs attention. We hope that citizens across the globe will increase their media literacy in this age of digitization to sustain global peace.
Today’s press conference is held by Green Party Taiwan as well we Miss Linda Arrigo, a former leader of Green Party Taiwan, and we are honored to be able to voice our opinion in advocacy of human rights, which is a core belief of the Green Party. The Green Party in Australia and in the US have also voiced their support for Julian Assange. We hope this press conference would invite more attention to issues surrounding Wikileaks’s future as well as damages that are being done to freedom of speech in Taiwan, such as fake news and misinformation. We hope such attention would create positive momentum to improve Taiwan.
