title: OpenCV - Possible Options for Image Compression
body: <p>thanks for taking the time to read my post. </p>
  
  <p>I'm working on a little project that is going well but as an optimisation exercise I would like to reduce the size of some of the JPEG's i'm outputting. At the moment, I have a .jpg that is 600 x 400 that is about 80kb. </p>
  
  <p>I have read about 32-bit, 8-bit images being signed, unsigned and floats and char's, along with BGR and YUV colour spaces and am not sure which are the factors that most affect size. </p>
  
  <p>Could anybody suggest where I might start to reduce this file size? </p>
  
  <p>I will of course play about and conduct my own tests to find the right image quality to file size balance.</p>
  
  <p>Many thanks in advance, 
  Kay</p>
