title: Histogram Normalization Features
body: <p>I am confused how I extract features using histogram normalization. Maybe this sounds too silly but sorry about been silly I am just confused. I have normalized the image but how i represent it as a feature. Is it the histogram becomes the feature or is it the concept of HOG (histogram of Oriented Gradient). I am confused how I represent histogram as a features. Can I get some explanation on this please.</p>
