This is my simple code:

ocr_result = mat_eng.ocr(image_matlab,'Language','ChineseTraditional','TextLayout','Word');
print("ocr_result: ", ocr_result, ".")

I am using python and working with MATLAB library ocr. After the scanning, I get a <matlab.object object at 0x7fc0908e9490> for each word. I am trying to get its string information contains in "Text". However, I cannot directly use ocr_result.Text. it would report an error: AttributeError: 'matlab.object' object has no attribute 'Text'. How can I extract the string information out?

在 MATLAB Online 中打开

I tried an OCR example as mentioned here. You can modify the code and try it like this:

import matlab.engine
eng = matlab.engine.start_matlab()
img = eng.imread('businessCard.png')
eng.workspace['ocr_text'] = eng.ocr(img)
print(eng.eval['ocr_text.Text'])

The parameters you have used in ocr function can be specified here as well normally as you have done. Just save the ocr object returned to matlab workspace and then access the text value from the object by eval function call.

Hope this helps!
