boundary detection 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

维纳滤波，能滤除干扰噪声，提取有用信号。但是当输入信号的统计特性偏离设计条件，它就不再是最佳的了，这在实际应用中受到了限制。 (Wiener filter, to filter out interference noise, extract the useful signal. However, when the statistical characteristics of the input signal deviates from the design conditions, it is no longer optimal, which has been limited in practical application.)
