  • OCR preprocessing filters for handwritten digits

    From denis@21:1/5 to All on Sun May 1 06:44:05 2016
    Has anyone used filters in skim to preprocess e.g. the handwritten MNIST digits before classification ? Links: https://en.wikipedia.org/wiki/Optical_character_recognition#Pre-processing lists various methods (with which I'm not at all familiar) http://stats.stackexchange.com/questions/30042/neural-networks-vs-support-vector-machines-are-the-second-definitely-superior/207951#207951
    has a picture of some hard-to-classify digits.
