contrast adjusment 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

有两个程序一个是关于frft的源程序，一个是应用frft对线性调频信号进行检测的程序，原理是以变换阶数（不同的分数阶域）为变量对观测信号进行分数阶变换，形成信号能量在时频平面上的二维分布，在此平面上按阈值进行峰值点的二维搜索即可检测线性调频信号并估计其参数。(There are two procedures one on frft the source, one application frft linear FM signal detection process, the principle is to transform the order of (different fractional domain) as the independent variables on the observed fractional signal change, the formation of signal energy in two-dimensional time-frequency plane distribution in this plane, the peak threshold value by two-dimensional linear FM signal can be detected search and estimate its parameters.)
