How is Optical Character Recognition ( OCR ) used in MATLAB?
Automatically Detect And Recognize Text In Natural Images. Use the ocr function from the Computer Vision Toolbox™ to perform Optical Character Recognition. Classify digits using HOG features and a multiclass SVM classifier. Run the command by entering it in the MATLAB Command Window. Web browsers do not support MATLAB commands.
How to train an OCR function to recognize a language?
Train the ocr function to recognize a custom language or font by using the OCR app Support files for optical character recognition (OCR) languages. Troubleshooting for Optical character recognition (OCR) ocr function Automatically Detect And Recognize Text In Natural Images.
How to use optical character recognition in Photoshop?
If the characters in the image are too close together or their edges are touching, use morphology to thin out the characters. Using morphology to thin out the characters separates the characters. Use binarization to check for non-uniform lighting issues. Use the graythresh and imbinarize functions to binarize the image.
