Polygon-assisted JPEG and MPEG compression of synthetic images

Marc Levoy
1995 Proceedings of the 22nd annual conference on Computer graphics and interactive techniques - SIGGRAPH '95  
We have experimented with textured versus untextured surfaces, fine versus coarse tessellation of curved surfaces, Phong versus Gouraud interpolated shading, and antialiased versus nonantialiased edges  ...  Recent advances in realtime image compression and decompression hardware make it possible for a high-performance graphics engine to operate as a rendering server in a networked environment.  ...  Adaptation could be based on block content hints from the model or importance hints from the application program.  ...

A survey on video compression fast block matching algorithms

Abir Jaafar Hussain, Zaynab Ahmed
2019 Neurocomputing  
The practical and widely method used to carry out motion compensated prediction is block matching algorithm.  ...  In this method, video frames are divided into a set of non-overlapped macroblocks and compared with the search area in the reference frame in order to find the best matching macroblock.  ...  An effective compromise is to adapt the macroblock size to the picture characteristics, for example choosing a large block size in the homogeneous and shade regions of a frame and choosing a small block  ...

Nikolce Stefanoski, Xiaoliang Liu, Patrick Klie, Jorn Ostermann
2007 2007 3DTV Conference  
Following the predictive coding paradigm, local temporal and spatial dependencies between layers and frames are exploited for compression.  ...  The algorithm decomposes each frame of a mesh sequence in layers employing patch-based mesh simplification techniques. This layered decomposition is consistent in time.  ...  Note that an error of 0.02 for Chicken and 0.15 for Cow can be regarded as lossless with regard to visual quality. In this domain STSLPC and FPC show best per-Chicken encoded using l =8 layers.  ...
