Vasileios Argyriou, Jesús Martínez del Rincón, Barbara Villarini, Alexis Roche · 2015
An overview of block-matching motion estimation methods is presented including the traditional methods such as full search, tree steps, diamond and the latest approaches. The same structure is used for hierarchical and shape-adaptive methods including registration methods based on quad-trees and the MPEG-4 or similar frameworks. Also, the main problems of registration for this application are discussed, indicating the particular research and development issues. The concepts of quality of system and quality of experience are discussed, and how image and video quality is influenced by the registration techniques is analysed. Quality metrics are presented focusing on coding applications.
