We develop an algorithm for blind facial image quality assessment using the texture descriptors of the histogram locally and any of the extracted features in blinds-II in the DCT domain. This paper proposes a quality assessment algorithm based on the extracted features from the important blocks in the distorted facial image, and then these features are used in a simple approach to predict quality scores. Experimental results are shown to correlate highly with human’s judgments of quality.
