Looking at thresholded characters

Just for kicks, this is what the training images look like as binary images. The top row is the 8-bit image and the bottom row is the binary image.



And b's, as always:


Here all I have to store are the non-zero indices, as opposed to storing the whole image, which is beneficial. And now I should center these characters! (Subtract off the centroid... why is that so hard?!)
