VB.NET获取圆角矩形 能获取一个圆 和圆心坐标 也能获取矩形(VB.NET Get the Rounded Rectangle To obtain the coordinates of a circle and the center of the circle can also obtain the rectangular)

In order to capture the spatial dependence of gray-level values which contribute to the perception of texture, a 2d dependence matrix known as a gray-level co-occurrence matrix is extensively used in texture analysis.So, this is a code that calculate a co-occurrence matrix of the image and return the following features: ENERGY, CONTRAST, CORRELATION and HOMOGENEITY.
