Quality Assessment for Image Using Perceptual Image Processing

R. Jayakumar, R. Janarthanan

Abstract


Assessment is a process of verifying and validating the quality of an image 1. Meets the academic and technical requirements that guided its quality, and 2. Works as expected. Image Quality also identifies important defects, flaws that must be fixed. During assessment we have to concentrate on perceived image degradation. An important characteristic is the comparison of an image with a perfect image that helps the usability or functionality of the application.

Assuring quality is not a responsibility of the designing team. The designing team cannot improve quality; they can only measure it. The perceptual image processing involves define perceptual IQA measures and optimize IP systems. Mean Squared Error (MSE) does not agree with human visual perception. This paper demonstrates the different methodologies used to check the image quality for better implementation.
