Abstract:
The paper presents a new no reference quality assessment algorithm for screen content image based on support vector regression. Firstly,we calculate the edge map through the difference of Gaussians,which is further used to extract edge features. Secondly,we obtain the luminance map through the local normalization,which is further used to compute luminance features. Finally,we map the quality-aware features to subjective scores through the support vector regression algorithm. Experimental results on two data sets show that the performance of the proposed algorithm is better than those of the most of the existing algorithms.
