Avaliação objetiva da qualidade de vídeo baseada na relevância dos objetos nos quadros

Abstract

This work presents the study, improvement and implementation of an algorithm to evaluate the video quality based on the relevance of objects in the frames. The measurements used to estimate the relevance requires a segmentation of objects. The work was divided into the following sections: (1) segmentation, (2) evaluation of segmentation and estimation of relevance, (3) generation of artifacts in video original and (4) evaluation of video quality. Experiments with different artifacts prove the efficiency of the proposed metric in terms of correlation with subjective measures
