ABSTRACT This proposal encompasses an objective video quality measurement method to automatically measure the perceived quality of a stream of video images. The method is based on a combined measure of distortion- invisibility, block-fidelity, and content richness fidelity. There is a need for automatic and objective video quality measurement method that is able to emulate the human vision to detect the perceived quality of a video stream. Traditionally, video quality is performed via a subjective test where a large number of human subjects are used to gauge the quality of a video but this process is not only time-consuming but and tedious and expensive to perform. This proposal describes an objective video quality measurement method for automatically gauging the perceived quality of a stream of video images using a combined feature of distortion-invisibility, block-fidelity, and content richness fidelity. It basically replaces the need of a subjective test in order to be able to gauge the perceived quality of a video stream. 2. INTRODUCTION Besides on-line and off-line visual quality evaluation, how distortion is gauged also plays a determinative role in shaping most algorithms for image and video manipulations, such as enhancement, reconstructio
