Abstract:
Measurement of visual quality is of fundamental importance
to numerous image and video processing applications. The
goal of quality assessment research is to design algorithms
that can automatically assess the quality of images. This
paper introduces an image quality index Visual region of
interest Weighted Structural Similarity (VroiWSSI). The
index integrates the notion of Visual regions of interest
with the measurement of structural similarity to effectively
match with Human Visual System (HVS). The method evaluates
the structural similarity between the original image and the
distorted image to arrive at structural similarity index in
a local region. The indices are then weighted based on the
Visual regions of interest characterized by entropy in the
local region that emphasizes the texture variance. VroiWSSI
of the image is calculated by averaging these weighted
indices. Test results show that VroiWSSI correlates well
with subjective scores.
