title: A guide to convert_imageset.cpp
body: <p>I am relatively new to machine learning/python/ubuntu.</p>
  
  <p>I have a set of images in .jpg format where half contain a feature I want caffe to learn and half don't. I'm having trouble in finding a way to convert them to the required lmdb format.</p>
  
  <p>I have the necessary text input files. </p>
  
  <p>My question is can anyone provide a step by step guide on how to use <code>convert_imageset.cpp</code> in the ubuntu terminal?</p>
  
  <p>Thanks</p>
