Digital color halftoning
(IEEE-INST Electrical Electronics Engineers Inc, 2005-01)
Digital color halftoning is done to create the perception of a continuous-tone color image using the limited spatiochromatic discrimination capability of the human visual system. Several techniques to perform this task are ...
Predictive vector quantization of 3-D mesh geometry by representation of vertices in local coordinate systems
(Elsevier Inc, 2007-08)
In predictive 3-D mesh geometry coding, the position of each vertex is predicted from the previously coded neighboring vertices and the resultant prediction error vectors are coded. In this work, the prediction error vectors ...
Fast algorithm analysis and bit-serial architecture design for sub-pixel motion estimation in H.264
(World Scientific Publishing Company, 2010-12)
The sub-pixel motion estimation (SME), together with the interpolation of reference frames, is a computationally extensive part of the H.264 encoder that increases the memory requirement 16-times for each reference frame. ...
