title: Convolutional Neural Network for time-dependent features
body: <p>I need to do dimensionality reduction from a series of images. More specifically, each image is a snapshot of a ball moving and the optimal features would be its position and velocity. As far as I know, CNN are the state-of-the-art for reducing the features for image classification, but in that case only a single frame is provided. Is it possible to extract also time-dependent features given many images at different time steps? Otherwise which is the state-of-the-art techniques for doing so?</p>
  
  <p>It's the first time I use CNN and I would also appreciate any reference or any other suggestion.</p>
