这是一个Matlab实现的隐马尔科夫树模型，用于计算图像的Contourlet系数。程序同时还包括图像去噪、纹理恢复的应用模型。-This is a Matlab realization of Hidden Markov Tree Model, used to calculate the coefficient Contourlet images. Program also includes image denoising, texture restoration of the applicat

An algorithm is proposed to split a single-pixel-width connected line graph into line segments by the Hit-and-Miss transformation (HMT). Firstly, junction points and free end points are detected by a set of HMTs. Then, line segments are traced betwee
