we are doing pan OCR, using tesseract but is not able to detect the details like name and pan number

Question

We are cropping the pan card image by increasing the height by 20px for every iteration and then we are passing that image to tesseract to do ocr but we are getting noise with output.if you have better solution on Image processing or another libraries like cv2 then please help us.

import pytesseract
from PIL import Image, ImageEnhance, ImageFilter

im = Image.open("image/testpan.jpg")
width = im.size[0]
height = im.size[1]
print('width,height-->',width,height)

yy='img'
zz='.jpg'

x=0
for j in range(x,height):
    img2 = im.crop((0, x, width/2,x+70))
    img2.save(yy+str(j)+zz)

    img = Image.open(yy+str(j)+zz)
    # img = img.convert("L")
    img.save(yy + str(j) + zz)
    text = pytesseract.image_to_string(Image.open(yy+str(j)+zz))
    print('IIIII',j, text)

    x=x+20
    j=x
    if j>height:
        break

Answer 1

Does this ok?

1. convert to gray
2. threshold
3. findContours
4. boundingRect
