equalizer and compression and show the filter analysis at matlab, you can set the filter by using the equalizer

用HOUGH检测直线的时候是两个未知量,因为轴半径和相角可以确定一条直 线，在HOUGH域出现累计最大点就可能是原域中的直线。现在回到圆的检测 上来，确定一个圆需要什么：X坐标，Y坐标，半径三个未知量吧，好了，现在， 你做一个三维空间的HOUGH域，以这三个未知量作为三个轴，现在按照一定步长 进行三重循环，在最内层循环是这样的，X,Y 确定，以不同的半径进行搜索，如 果你的X,Y刚好就是实际图像的X,Y处，半径又搜索到实际真实的半径(The HOUGH detect straight when two unknown amount of axis radius and phase angle can be determined in a straight line, in the HOUGH domain cumulative maximum point may be the straight line of the original domain. Now back to the circle detection up to determine what a circle: X coordinate, Y coordinate, radius three unknowns, now, you do the HOUGH domain of a three-dimensional space, three to three unknown quantity as axis, in accordance with a certain step size triple loop, is such that in the innermost loop, X, and Y determined search for a different radius, If you X, Y, exactly is the actual image of the X, Y, at the radius radius of the search to the actual real)

matlab 鼠标从一幅图像中截取一个区域，并生成一幅图片(get a picture form a picture)

对二维结构进行拓扑优化，基于变密度法的二维mbb梁的结构拓扑优化，迭代采用优化准则法，数值不稳定采用灵敏度过滤法。(Two-dimensional structure topology optimization, based on the variable density method of two-dimensional the MBB beam structure topology optimization, iterative optimization criteria, the numerical instability sensitivity filtration.)
