CAPTCHA (驗證碼) OCR 前置處理 - 去噪、補點 (Python). Jun 22, 2014. OCR 在網路上已經有相當多的 module 可以直接使用，以我來說，我是用 tesseract，也有人寫好了 python-tesseract 可以直接調用，相當方便。 但以正常情況來說，如果要對驗證碼做 OCR 的話，驗證碼本身會有許多雜訊干擾，導致 OCR 失敗。 Enhancer = ImageEnhance.Contrast(im). Im = enhancer.enhance( 3.0. Enhancer = ImageEnhance.Brightness(im). Im = enhancer.enhance( 10.0. 可以看到明顯有顏色的部份只剩下字體和框線，而且根據 pixel value 的觀察由於圖像是 RGBA，字體的部份 B = 255，邊緣部分則有些為的 Alpha。 Pix[x , y][ 1.

Python 語音辨識 · Steven5538 Said：

May 22, 2015. Sudo pip install SpeechRecognition. 該套件利用 Google Speech Recognition API 去實現語音辨識的功能，所以網路功能是必須的。 R = sr.Recognizer(). Audio = r.record(source). Print( "Could not understand audio". R = sr.Recognizer( 'zh TW'. Renergy threshold = 4000. 4000 可以自行調整(官方說 4000 效果就很好了)。
