Descr iption: A faster implementation of binary dilation and erosion.
Our functions take advantage of MATLAB s decomposition of the structuring element but they may result much faster. Try to run example.m to see the speed improvement factor, c

Binary erosion and dilation, with fast iterative calls.
For any structuring element other than square or disk this function is way faster than imerode.m and imdilate.m (more than an order of magnitude). It s also handy when you don t have the M

The basic steps of the edge-based text extraction algorithm are given below
1. Create a Gaussian pyramid by convolving the input image with a Gaussian kernel
and successively down-sample each direction by half. (Levels: 4)
2. Create directiona

填补圈子之间的“漏洞”。 首先尝试使用半径为7的圆盘结构元素来关闭圆形图像，除了填充孔之外，还要附上结果图像以及您观察到的任何副作用。(Fill up the "holes" in between the circles.First try closing the circle image by a disk structuring element with radius 7, attach the result image and any side-effects you

Dilation is one of the basic operations in mathematical morphology. Originally developed for binary images, it has been expanded first to gray scale images, and then to complete lattices. The dilation operation usually uses a structuring element for
