I have a hexadecimal text X='ABCD1234', i wirte it into an image I='Background.bmp' using : >> p=[1 1]; >> IMG= rgb2gray(insertText(I,p,X,'Font','Arial Black','FontSize',23,'TextColor','Black')); then, i am trying to get this text back from the image using the built-in function OCR like this: >> I=imresize (I,[2.5*R C]); I=imbinarize(I); >> ocrtxt=ocr(I,'TextLayout','Word','Characterset','0123456789ABCDEF'); Recovered_txt=ocrtxt.Text; But it always gives me errors like: it reads 'A' as '11', 'B' as '8', 'D' as '0'. what is the best (font name) and (font size) for best results?
