Video summary generation and coding using temporal scalability
Ferreira, Lino; Cruz, Luís; Assunção, Pedro AmadoIn this paper two algorithms for video summary generation and coding are proposed. Two distortion metrics used in the video summary generation algorithm are compared and an algorithm with reduced computational complexity is presented. The paper also proposes two frame structures in the temporal domain suitable for coding using temporal scalability of the H.264/SVC.
H.264/SVC ROI encoding with spatial scalability
Ferreira, Lino; Cruz, Luís; Assunção, Pedro AmadoComunicação apresentada na International Conference on Signal Processing and Multimedia Applications, Porto, 2008. ; This paper proposes two H.264/AVC compliant methods for encoding Regions-of-Interest (ROI) with spatial scalability and evaluates their respective rate-distortion-complexity performance. The base layer is kept unchanged and provides lower resolution images with roughly constant quality, without ...
