Use ROI for images color indexing. #4

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
From google paper.

"Many of the features values below are computed for a region of interest (ROI) 
in the image, which is a rectangle centered in the image, inset by of the 
original image dimensions on all sides. The size of this ROI was determined 
empirically."

Will need to take in effect in next version of gallery. Color indexer CPP 
application and PHP version. Should provide a little bit more precise color 
search results.
