The objective measurement of blocking artifacts plays an important role
in the design, optimization, and assessment of image and video coding
systems. We propose a new approach that can blindly measure blocking
artifacts in images without reference to the originals. The key idea is
to model the blocky image as a non-blocky image interfered with a pure
blocky signal. The task of the blocking effect measurement algorithm is
then to detect and evaluate the power of the blocky signal. The proposed
approach has the flexibility to integrate human visual system features
such as the luminance and the texture masking effects.
