Analysis and Comparison of Compression Algorithm for Light Field Mask
This paper describes comparison and analysis of state-of-theart lossless image compression algorithms for light field mask data that are very useful in transmitting and refocusing the light field images. Recently, light field cameras have received wide attention in that they provide 3D information. Also, there has been a wide interest in studying the light field data compression due to a huge l...
متن کاملData compression for light-field rendering
Two light-field compression schemes are presented. The codecs are compared with regard to compression efficiency and rendering performance. The first proposed coder is based on video-compression techniques that have been modified to code the four-dimensional light-field data structure efficiently. The second coder relies entirely on disparity-compensated image prediction, establishing a hierarc...
متن کاملMulti-hypothesis Prediction for Disparity-compensated Light Field Compression
In this paper, we describe a multi-hypothesis prediction technique for disparity-compensated light field compression. Multihypothesis prediction has been used extensively in video compression. In this work, we apply multi-hypothesis prediction to the problem of light field compression. Most current techniques for light field compression utilize some form of disparity compensation with one hypot...
متن کاملCompression for Full-Parallax Light Field Displays
Full-parallax light field displays utilize a large volume of data and demand efficient real-time compression algorithms to be viable. Many compression techniques have been proposed. However, such solutions are impractical in bandwidth, processing or power requirements for a real-time implementation. Our method exploits the spatio angular redundancy in a full parallax light field to compress the...
متن کاملTheoretical analysis of geometry inaccuracy for light field compression
In current light field compression algorithms, geometry information is critical for efficient compression of light field image data. Inaccuracies in the geometry can greatly affect the compression efficiency. In this paper, we present a theoretical framework with which we can analyze and understand the effects of geometry inaccuracy on the compression efficiency of a light field coder. This fra...
