说明：  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.)

jquery.easing.js 1.3 是一个配合jquery实现完美动画效果的扩展插件，比如我们在使用jquery制作一幅图片滚动或图片渐变，使用本插件可扩展或增强jquery性能，生成完美无缺兼容性更好的jquery动画来，它不仅可以用于图像特效，像一些基础的层操作也可以使用。(jquery.easing.js 1.3 is a perfect fit jquery animated extensions, such as we use jquery make a picture or a picture scroll gradient, using this plugin jquery enhanced scalability or performance, generate flawless compatibility and better jquery animation, which not only can be used for image effects, like some basic layer operations can also be used.)
