Paper Abstract

The advantages and disadvantages of conventional image quality evaluation methods are analyzed and according to the characteristics of laser disturbing image, an image quality evaluation method which is based on wavelet weight and correlation is established. In the method, both the original and disturbed images are processed by wavelet decomposition, replacement and reconstruction. Then different sub-band images are obtained and their correlations are calculated. Combined with band-pass characteristic of human vision, visual weighted coefficients are obtained and objective calculation results are output finally. Experimental results show that this method not only can overcome the influences of different conditions on evaluation of laser disturbing effect, but it is also in good agreement with the subjective method.
