应用背景在图像处理中，有时需要将真彩色图像转换到其他色彩空间进行处理，已获得更好的处理结果，即从RGB空间转换到LAB或者HSI空间等，处理后为迎合人眼需求一般要将其他色彩空间的处理结果再次转换到RGB空间。本代码即实现了RGB与LAB的互转。关键技术 在色彩空间的正向转换中（RGB to LAB）:采用的是九级均匀分割建模，棱柱差值； 在反向转换中（LAB to RGB）：采用的是多项式回归方法。

对于一些图像来说，常用的边缘检测算法有时候无法设立合适的阈值将它们的梯度较小的模糊边缘检测出来。为了解决这个问题，有两种解决方法：将图像方差标准化，拉大模糊边缘的梯度值，或通过设置sigmoid函数，将像素所在区域的信息传递到梯度值中去，对其进行调整，就能找到合适阈值，有效地将模糊边缘提取出来。本程序把这两种算法实现并与与传统算法进行了比较。-For some images, the commonly used edge detection algorithm sometimes can not be an appropriate threshold for the gradient of their smaller fuzzy edge detected. To solve this problem, there are two solutions: the image variance standardization, widening the fuzzy edge of the gradient value, or by setting the sigmoid function pixel region to disseminate the message to the gradient values to adjust, on the can find a suitable threshold, effectively extracted fuzzy edge. This procedure of these two algorithms with the traditional algorithm.
