The scalable video coding H.264/SVC is the video coding standard which is an extension of H.264/AVC. Because of its scalability, H.264/SVC has gained a great interest in video transmission. Partial bit stream can be transmitted and decoded by the H.264/SVC in order to provide quality in lower temporal or spatial resolutions or reduced fidelity while retaining a reconstruction quality that is high...
H.264 video coding standard offers several coding modes including inter-prediction modes that use macroblock partitions with variable block sizes, Choosing a rate-distortion optimal mode among these possibilities contributes significantly to the superior coding efficiency of the H.264 encoder. Unfortunately, searching for optimal motion vectors of each possible subblock incurs a heavy computational...
Atomic decompositions have been increasingly used as signal compression tools. In general, these decompositions are obtained using a single dictionary. One may use instead several dictionaries to decompose the signal, and transmit side information in order to indicate the dictionary employed. This allows the selection of the dictionary leading to the best rate-distortion compromise. Such a scenario...
Remote navigation in compressed image-based scene representations requires random access to arbitrary parts of the reference image data to recompose virtual views. The degree of inter-frame dependencies exploited during compression has an impact on the effort needed to access reference images and delimits the rate distortion (RD) trade-off that can be achieved. If, additionally, a given receiver hardware...
