Hi everyone, I need some help about this question. I have choose optical character recognition (OCR) for my Signals and Systems course but I couldn't find anything which feature extantion matlab uses for that. I mean, what happen after when I use "ocr" on matlab? How does it find the character on the image. Which feature extension using on this method?

I have found some methods on the internet:

Fourier Transform
WaveletTransform
TemplateMatching
Zoning
Crossing and Distances
Projection Histogram
Zernike Moments
Moment Invariants

Which of the above methods does matlab use?
