title: Image centering before classification?
body: <p>I did a project at school where I had to classify objects into cats and dogs. I used SVM and logistic regression to achieve this. </p>
  
  <p>The images were given to us in the form of features. So we did not have to handle things like image centering and so on...</p>
  
  <p>My questions is, how do you center all the images so my classifier can learn better? I know CNN are good for this, but I would like to know just how to center the images before classification?</p>
  
  <p>Thanks!</p>
