Image Quality Assessment Based on Contourlet and ESD Method

In recent years, the development of the digital image processing promotes the research of the image quality assessment (IQA). A novel metric for full-reference image quality assessment is presented. The metric combined the contourlet transform with the energy of structural distortion (ESD), namely the CT-ESD. The calculation of the ESD is carried out in each subband of the contourlet transform. Then the comparisons between the reference and the distorted images on each subband are integrated by weighting sum. The superiority of the contourlet transform integrates well into new IQA metric. Experiments performed on the database TID2013 demonstrate that the CT-ESD can achieve high consistency with the subjective evaluation.
