Video sequences noise reduction are of great potential benefit to the video industry, as they promise the means to evaluate the performance of acquisition, display, coding and communication systems. Many researchers have focused on developing digital video sequences noise reduction methods. However, to be widely applicable a noise reduction must also work over a wide range of quality. In this paper,...
Accurate objective quality metrics are of great potential benefit to the video industry, as they promise the means to evaluate the performance of acquisition, display, coding and communication systems. Many researchers have focused on developing digital video quality metrics which produce results that accurately emulate subjective responses. However, to be widely applicable a metric must also work...
This paper presents a novel rate control initialization algorithm for H.264. Firstly the first instantaneous decoding refresh frame in a video sequence is intra-coded to get the mean absolute difference (MAD) value, then the average MAD value of the second, third and fourth frames which are inter-coded is computed, finally the initial quantization parameter is determined depending on the bits per...
Time-varying meshes (TVM) is a new 3-D scene representation which are generated from multiple cameras. It captures highly detailed shape and texture as well as movement of real-world moving objects. Compression is a key technology for supporting TVM applications such as education, interactive broadcasting, and intangible heritage archiving. Previous works focused on compression of 3-D animation that...
