Windows 將引入 TruePlay,推出作弊偵測的 API

在「Windows now includes gaming cheat detection at the system level」這邊看到微軟將會引入 TruePlay (然後跟 Sonos 的 trueplay 衝名 XDDD) 作弊偵測機制。 很明顯的會有隱私問題,而也很明顯的微軟說不會有隱私問題: As Microsoft notes, "to protect customer privacy, no data is shared or transmitted until permission is granted," and no information is … Continue reading

偵測 Chrome Headless

作者因為種種原因,想要偵測 Headless 模式的 Google Chrome:「Detecting Chrome Headless」。 之前因為主要是 PhantomJS,有很多地方跟一般的瀏覽器不同,可以利用這些不同的地方來判斷出是不是 PhantomJS: Until now, one of the most popular headless browser was PhantomJS. Since it is built on the Qt framework, it exhibits many differences compared to most popular browsers. As presented … Continue reading

把才能用在奇怪的地方:老闆偵測器

作者用 OpenCV 學習老闆的臉,然後當老闆走過來的時候把畫面切到努力工作中的 screenshot XDDD:「Deep Learning Enables You to Hide Screen when Your Boss is Approaching」。 “My boss left his seat and he was approaching to my seat.” “OpenCV has detected the face and input the image into the learned … Continue reading

Amazon Rekognition:圖片辨識 API

從 Google 的 Vision API,到 Microsoft 的 Computer Vision API (參考「微軟也推出圖片辨識的 API 了」),AWS 也推出類似的服務了:「Amazon Rekognition – Image Detection and Recognition Powered by Deep Learning」。 與其他兩家都是類似的方式,丟圖進去然後用系統已經 train 好的資料給你分析結果... 然後依照次數算錢。 有種算是補產品線的感覺啦...

NLP 的應用:PAN 2013

兩個禮拜前在 Slashdot 上看到的「When Writing, How Anonymous Can You Be, Really?」,提到了 PAN Workshop and Competition。 PAN 2013 將在明年九月辦,除了一般有的演講以及投稿以外,還包括了三個競賽: Plagiarism Detection Author Identification Author Profiling 三個題目都相當實用... 先紀錄起來,等明年九月再回頭來看?

隨機產生「臉」的 pareidoloop

在 Hacker News 上看到的玩具: 先隨機產生多邊形圖形。 丟到 Face detection library 偵測是否有臉,沒有找到的話就回到第一步,如果有的話就會有個匹配值 (fitness)。 如果有找到臉,就試著修改圖形 (進化) 找到更高的匹配值... JavaScript 寫的,可以在 browser 上直接跑。原始程式碼在「https://github.com/phl/pareidoloop」,可以用瀏覽器玩的網站在「pareidoloop」。 用基因演算符合 Face detection library 偵測的特徵,還蠻有趣的玩具... 這是跑了大約半個小時跑出來的臉 (還蠻小張的): 有些臉的感覺,不過因為只有黑白圖片,而且又小小張的,感覺有點像是靈異照片 XDDD 像是「八大真實靈異照片!」這邊的例子...
