no-reference image metric

Value range

(no blocks) 0..∞ (a lot of blocks)

Value interpretation

bigger is more blocks

-metr blocking

Algorithm description

This metric contains heuristic method for detecting objects edges, which are placed to the edge of the block. In this case metric value is pulled down, allowing to measure blocking more precisely. This metric also considers image contrast around of block and use it as weight for obtained value.
