ocr roi in matlab

The following steps can be used to perform OCR on ROI in Matlab:

1. Read the image containing the ROI

main.m
I = imread('image.jpg');
25 chars
2 lines

2. Define the ROI using the imrect function

main.m
hROI = imrect;
position = wait(hROI);
38 chars
3 lines

3. Crop the image using the ROI position

main.m
croppedImage = imcrop(I, position);
36 chars
2 lines

4. Perform OCR on the cropped image

main.m
ocrResults = ocr(croppedImage);
recognizedText = ocrResults.Text;
66 chars
3 lines

The variable recognizedText contains the recognized text.

Note: OCR accuracy depends on the quality of the input image. It may be necessary to pre-process the image before performing OCR.
