Acquisition and Encoding of High Dynamic Range Images using Inverse Tone Mapping
A two layer coding algorithm for high dynamic range images is discussed. In the first layer, a low dynamic range image is encoded by a conventional codec, and then the residual in...

Optimizing a 3D-FWT Video Encoder for SMPs and HyperThreading Architectures
In this work we evaluate the implementation of a video encoder based on the 3D Wavelet Transform optimized for HyperThreading technology and SMPs. We design several implementation...
