Abstract: The perceived quality of images reconstructed from low bit rate compression is severely degraded by appearance of transform coding blocking artefacts. It is of interest to be able to numerically assess the degree of blocking artefacts as it plays an important role in the design, optimisation and assessment of image and video coding systems. The proposed algorithm is based on new modelling function for blocking artefact detection in compressed images. Our experiment results show that the proposed method exhibits satisfactory performance as compared to other post-processing method's/techniques and is very efficient and stable since the signal need not be compressed/decompressed.
