Paddle OCR fail to extract single digit

I’m using Paddle OCR to extract prices from some products price tags, in most cases it give good results but I noticed that it fails to extract prices with single digit

enter image description here

When I edit the image and add a digit next to the first one, the algorithm succeed to extract the price

I’m using Python with the basic code took from PaddleOCR documentation

from paddleocr import PaddleOCR
ocr = PaddleOCR(use_angle_cls=True, lang='fr')
result = ocr.ocr(image_path, cls=True)
for line in result[0]:
    text = line[1][0] 
    position = line[0]
    print(text, position)

Is there an approach or specific configuration that I can use to extract prices with single digit ?

Solution

  • Increase the max_text_length value switch to lang=en and use det=True in the inference:

    
ocr = PaddleOCR(use_angle_cls=True,lang='en', max_text_length=50)
img_path = './p.jpg'
result = ocr.ocr(img_path, cls=True, det=True)

    Result:
