A Method for Rate Point Determination for Visual Evaluation of Video Sequences

Picture Coding Symposium, pp. 1–5

Abstract

This paper reports on the process of composing a set of test sequences for evaluation of responses to the Call for Evidence on video compression with capability beyond VVC currently prepared in the Joint Video Experts Team of ISO/IEC JTC 1/SC 29 and ITU-T SG21. The goal is to compose a test set covering the intended application spaces with associated challenging target bitrate values. These values are selected such that candidate coding schemes can be evaluated without saturation effects in the low or high visual quality ranges. After pre-screening candidate sequences, a novel succession test method is applied to efficiently determine viable rate points with distinct quality levels. The outcome is evaluated using the Degradation Category Rating (DCR) method. The applied succession test method was found to be useful and efficient for assessing the draft rate point allocation for the test sequences. Some refinement of the method might be explored in future experiments.
