摘要

从相机阵列收集的光场原始数据需要在磁盘上有很大的存储空间。为了压缩光场数据，稀疏表示被认为是首选方法之一。在本文中，我们设计了一个正交匹配追踪(OMP)处理器来改善寻找稀疏表示的计算时间。该芯片的工作频率为400mhz，与软件版本相比，速度提高了5倍。

An orthogonal matching pursuit processor for sparse-representation-based light field data compression

Light field raw data collected from a camera array require large storage space on disks. To compress light field data, sparse representation is regarded as one of the top choices. In this paper, we design an Orthogonal Matching Pursuit (OMP) processor to improve computing time for finding sparse representation. The chip operates at 400 MHz and achieves 5 times speed-up when compared to the software version.
