title: Neural Network Picture Classification
body: <p>I would like to implement a Picture Classification using Neural Network. I want to know the way to select the Features from the Picture and the number of Hidden units or Layers to go with.</p>
  
  <p>For now i have an idea of changing the size of image to some 50x50 or smaller so that the number of Features are less and that all inputs have constant size.The features would be RGB value of each of the pixels.Will it be fine or there is some other better way?</p>
  
  <p>Also i decided to go with 1 Hidden Layer with half the number of units as in Inputs. I can change the number to get better results. Or would i require more layers ?</p>
