Contrast is the difference in luminance or color that makes an object (or its representation in an image or display) distinguishable. In visual perception of the real world, contrast is determined by the difference in the color and brightness of the object and other objects within the same field of view. Because the human visual system is more sensitive to contrast than absolute luminance, we can perceive the world similarly regardless of the huge changes in illumination over the day or place to place. The maximum contrast of an image is the contrast ratio or dynamic range

该文档是一个比较简单的能够获得压缩感知稀疏解的matlab代码-OMP(正交匹配追踪),
通过离散傅里叶变换将时域接收信号变换到频域上,
得到接收信号的频域稀疏表示,通过OMP算法,求出稀疏解,
并通过重构信号误差衡量该算法代码的精确度。(This document is a simple matlab code -OMP (Orthogonal Matching Pursuit algorithm) by which the sparse solution of compressed sensing can be obtained.
Firstly, signals received are transformed from the time domain to the frequency domain by the discrete Fourier transform.
Secondly, sparse solutions of received signals are obtained by OMP algorithm.
Finally, reconstruction error depicts the accuracy of the algorithm.)
