Major Coefficients Recovery: a Compressed Data Gathering Scheme for Wireless Sensor Network
Coefficients Data Gathering Wireless Sensor Network
2012/12/4
For large-scale sensor networks deployed for data gathering, energy efficiency is critical. Eliminating the data correlation is a promising technique for energy efficiency. Compressive Data Gathering ...
Macroblock-Level Adaptive Scan Scheme for Discrete Cosine Transform Coefficients
Macroblock-Level Discrete Cosine Transform Coefficients
2010/12/17
Discrete Cosine Transform (DCT) has been widely used in image/video coding systems, where zigzag scan is usually employed for DCT coefficient organization. However, due to local
diversity of predicti...
Macroblock-level Reduced Resolution Video Coding Allowing Adaptive DCT Coefficients Selection
Video Coding DCT Coefficients Selection
2010/12/17
Reduced Resolution Update (RRU) video coding provides a better compression performance than H.264/AVC does. It is implemented by encoding the predicted residuals after downsampling
at the encoder and...
