The numerical data are different each time). > - Provide the screenshot to Tesseract to extract the data. My strategy > is to remove the vertical and horizontal lines in the table, extract the > entire text, and collect the numerical values corresponding to the labels I > want to capture. > - Finally, generate a text output based on the extracted data. > > The app works fine, but there are still many errors in data extraction. > Sometimes, some values are not extracted at all because the label is not > correctly recognized.
