Make it analyse images

[MatEdwards]

Look at past code and attempt to analyse a image using the same sort of commands. May want to communicate with person doing calculations to figure out best commands to use

Design an opencv filter pipeline.

[ounsworth]

Proposed pipeline:

• Yellow threshold (& B&W cleanup like erode/dilate) --> Binary Mask
• extractContours() --> list of non-touching objects
• for each contour (object):
  • Apply binary mask to colour img with ROI bounding box from contor
  • toGrayscale()
  • cleanup ?
  • Canny edge detect & Corner detect

(we may find that we don't need the corners, the centre of each cube blob might be enough, so we could stop at the extractContours() step)
