Hello,

I have a picture with text written on it and ocr doesn't work on it

I = imread('image1_bw.png');

imshow(I);

roi = [117,82,307,213];

hold on

rectangle('Position',roi,'EdgeColor','r')

hold off

text=ocr(I,roi)

text =

ocrText with properties: Text: 'OPO↵Ot↵ONO↵PENG↵↵' CharacterBoundingBoxes: [17×4 double] CharacterConfidences: [17×1 single] Words: {4×1 cell} WordBoundingBoxes: [4×4 double] WordConfidences: [4×1 single] TextLines: {4×1 cell} TextLineBoundingBoxes: [4×4 double] TextLineConfidences: [4×1 single]

I should add that on my machine the result is different as I get

Text: ''

Probably because the version is different I'm using the 2021a release and the version 10.0 of the computer toolbox

I have no idea why ocr is not working in this case. If someone has a fix it will be very helpfull :)
