Towards the new concept of linear image quality assessment. Review of phase correlation formulas
Przemysław Skurowski · 2015
The article reports the progress in a development of an image quality assessment (IQA) method based on a new concept – phase correlation. The primary idea stems from the classical observation that structural information of the media/image information is stored within the phase part of the Fourier spectra. The paper describes the review and selection process of a correlation formula for future full reference IQA method. The results were verified with reference database against the human visual quality responses given in mean opinion score (MOS) scale, whereas the key goal was to keep the linearity of the results as it was observed in preliminary results. There were tested correlation models linear and circular raw and weighted in using various weighting schemes.
