Previously I had trained a
Neural Networkupon 20,000 character images. This
Neural Net generally works well, it uses
RGB- Hue, Saturation, Intensity feature set for training. However, there can be certain character images which have
RGB-HSI values that this
neural net has not seen before. Therefore I am looking forward to converting training data to
grayscale and use some feature set well suited for grayscale images.
So are there any good suggestion for extracting a feature set out of
