Paper Abstract
In our work, we introduce the block significance measure reflecting
the property of the blocks to be shared by pixels from different image
regions. The blocks B with higher significance value C(B) belong to
the fields of region contrast and thus tend to attract more attention
in terms of the Human Visual System (HVS). The computation of C(B) is
based on the execution of a region merging procedure and determination
of the first partitioning containing a region completely covering
a block B. The introduced measure is related to the flat/texture/edge
block classification but reflects global image properties and differs
from the latter. We study how one may incorporate the measure in the
DCT-based based image/video compression. Experimental results are
presented.
