How can define character size for tesseract?

[ali madad]

Dear researchers,

when I use tesseract for character recognition, there exist so many wrong results which the character width or height is about 4 pixels.

Is there any way to restrict the tesseract recognition by a range of character size?

thank you very much for your time.

From your problem, it seems to be like you are trying to extract text from small image, like an image that contains very less characters or may be a single word. For improving the accuracy, you can use the PSM(Page Segmentation Mode) option. Tesseract comes with 12 different psm modes. The usage can be as:

tesseract.image_to_string(image,lang='eng', config='--psm 8')

psm 8: Consider the image as a single word in it

psm 7: Consider the image that has a single line in it

By default, tesseract uses psm 3
