这个是图像轮廓提取的matlab程序，而且提取完后还能把所有轮廓用不同颜色分开存放到轮廓矩阵cell中，方便用户对感兴趣的轮廓进行操作--张璐奉献(This is the matlab image contour extraction process, but also exhausted all the contours extracted with different colors kept separate from the profile cell in the matrix, user-friendly to operate the contours of interest- Zhang Lu dedication)

直方图均衡：原始图的直方图变换为均匀分布的形式，这样就增加了象素灰度值的动态范围从而达到增强对比度的效果 中值滤波：中值滤波属于非线性平滑滤波器，它可以消除噪声又能保护图象的细节(histogram equalization : the original plan to transform the histogram in the form of uniform distribution. This will increase the value of the pixel gray areas so as to achieve dynamic contrast enhanced effect of filtering : Median filter is nonlinear smoothing filter, it can eliminate noise while preserving image details)

说明：  his work proposes two novel optimization algorithms called Salp Swarm Algorithm (SSA) and Multiobjective Salp Swarm Algorithm (MSSA) for solving optimization problems with single and multiple objectives. The main inspiration of SSA and MSSA is the swarming behaviour of salps when navigating and foraging in oceans. These two algorithms are tested on several mathematical optimization functions to observe and confirm their effective behaviours in finding the optimal solutions for optimization problems.

说明：  非线性方程的求解，包括牛顿法，两点割线法，数值延拓法，等等(nonlinear equation)
