I'm trying to use the orc function in this way
"ocrRes = ocr(businessCard,'Language','C:\Users\Gio\Desktop\OCR\tessdata\spa.traineddata');" and have this error
Error using tesseractWrapper Internal error using Tesseract
"ocrRes = ocr(businessCard,'Spanish','C:\Users\Gio\Desktop\OCR\tessdata\spa.traineddata');"
Error using ocr>parseInputs (line 209) The argument 'Spanish' is a string scalar or character vector and does not match any parameter names. It failed validation for the argument 'ROI'.
Could you help me Please....

At the command line give the command
dbstop if caught error
then run your code. MATLAB will detect some processing error or other, and in the command window it will tell you what the error was and where the error occurred. You should copy that information and paste it here.
For example it might complain about an index our of range, or about array dimensions mismatch.

ocrRes = ocr(businessCard, 'Language', {'Spanish', 'C:\Users\Gio\Desktop\OCR\tessdata\spa.traineddata'});
However it is not clear if it is possible to use both a language name and a path at the same time. You might need
ocrRes = ocr(businessCard, 'Language', 'C:\Users\Gio\Desktop\OCR\tessdata\spa.traineddata');

Thanks but, I found another mistake, I need the OCR to look only for words in Spanish.

Error using ocr>parseInputs (line 215)
The argument 'PRO' is a string scalar or character vector and does not match any parameter names. It failed validation for
the argument 'ROI'.
Error in ocr (line 119)
[roi, hasROI, params] = parseInputs(I,varargin{:});
Error in Untitled (line 9)
b=ocr(a,'PRO','C:\Users\mian adil\Desktop\PRO\tessdata\PRO.traineddata')
i need your help to solve this
