Python-tesseract 是光学字符识别Tesseract OCR引擎的Python封装类。能够读取任何常规的图片文件(JPG, GIF ,PNG , TIFF等)并解码成可读的语言。在OCR处理期间不会创建任何临文件。
示例1：
import tesseract api = tesseract.TessBaseAPI() api.Init(".","eng",tesseract.OEM_DEFAULT) api.SetVariable("tessedit_char_whitelist", "0123456789abcdefghijklmnopqrstuvwxyz") api.SetPageSegMode(tesseract.PSM_AUTO) mImgFile = "eurotext.jpg" mBuffer=open(mImgFile,"rb").read() result = tesseract.ProcessPagesBuffer(mBuffer,len(mBuffer),api) print "result(ProcessPagesBuffer)=",result示例2：import cv2.cv as cv import tesseract api = tesseract.TessBaseAPI() api.Init(".","eng",tesseract.OEM_DEFAULT) api.SetPageSegMode(tesseract.PSM_AUTO) image=cv.LoadImage("eurotext.jpg", cv.CV_LOAD_IMAGE_GRAYSCALE) tesseract.SetCvImage(image,api) text=api.GetUTF8Text() conf=api.MeanTextConf()
