问题描述
我需要使用 Pytesseract 从这张图片中提取文字:
I need to use Pytesseract to extract text from this picture:
和代码:
from PIL import Image, ImageEnhance, ImageFilter import pytesseract path = 'pic.gif' img = Image.open(path) img = img.convert('RGBA') pix = img.load() for y in range(img.size[1]): for x in range(img.size[0]): if pix[x, y][0] < 102 or pix[x, y][1] < 102 or pix[x, y][2] < 102: pix[x, y] = (0, 0, 0, 255) else: pix[x, y] = (255, 255, 255, 255) img.save('temp.jpg') text = pytesseract.image_to_string(Image.open('temp.jpg')) # os.remove('temp.jpg') print(text)
和temp.jpg"是
and the "temp.jpg" is
还不错,但是打印的结果是,2 WW不是正确的文本2HHH,那我怎样才能去除那些黑点呢?
Not bad, but the result of print is ,2 WW Not the right text2HHH, so how can I remove those black dots?
推荐答案
这是我的解决方案:
import pytesseract from PIL import Image, ImageEnhance, ImageFilter im = Image.open("temp.jpg") # the second one im = im.filter(ImageFilter.MedianFilter()) enhancer = ImageEnhance.Contrast(im) im = enhancer.enhance(2) im = im.convert('1') im.save('temp2.jpg') text = pytesseract.image_to_string(Image.open('temp2.jpg')) print(text)
