In this paper, we present a computational and memory efficient no-reference (NR) image quality assessment models for JPEG and JPEG2000 color images and also present the discrimination algorithm of these two types of images, which are applicable to various image processing applications. The proposed models and algorithm are based on blockiness around the block boundary and activity measure of the image signal within block of the image. Subjective experiment results on the two types of images are used to train the models, that achieves good quality prediction performance, and the models are also tested on a test database.
