Measurement coding compresses the output of compressive image sensors to improve the image/video transmission efficiency. In these coding systems, rate control plays a vital role. The major purpose of rate control is to determine the quantization paramet

As shown on the left of Figure 3-6, we found the access pattern of the Laplacian matrix accumulation in K1 was similar to the one in K2 while using the Laplacian matrix, so we move the accumulation to K2 to simplify K1's data access pattern for better cache hit ...
WaveVideo is an integrated, adaptive video coding architecture designed for heterogeneous wireless networks. It includes basic video compression algorithms based on wavelet transformations, an efficient channel coding, a filter architecture for receiver-based media scaling, and error-control methods to ...

. For example, the encoder 220 can encode the input stream at a first bitrate, resolution, and/or frame rate and can output the encoded stream as a first output stream (e.g., 240a). In embodiments, the encoder 220 can use information obtained from encoding the input stream at the ...
For example, an HEVC video bitstream may include one or more CVSs including NAL units. Each of the NAL units has a NAL unit header. In one example, the header is one-byte for H. 264/AVC (except for multi-layer extensions) and two-byte for HEVC. The syntax elements in the NAL unit...
