subpixel

实现图像的方差，斜度，峰度，能量和熵的实现，代码简单，可以直接运行(matlab graph variance)

实现对邮票中手写字符的提取，得出灰度直方图，平滑算法，锐化算法以及输出二值化图像(Realization of the extraction of handwritten characters in stamps)

改进陈显毅GUI程序,可实现对异模情况下的配准，对边缘较明显的图片用处很大(The improvement of the Chen GUI program)

说明：  利用最大间类差，最优阈值，迭代阈值等方法实现图像分割(The maximum class difference, optimal threshold and iterative threshold are used to realize image segmentation)

说明：  n个点电荷电场线的matlab仿真 分别有1个 2个等（可以通过改变程序数字来得到相应的仿真结果）(Matlab simulation of N-point charge electric field lines)

说明：  基于区域的分裂合并图像分割方法，包含三个m文件，predicate是分裂合并准则代码，split_test用于检测是否需要分裂，splitmerge用于分裂合并(Region Based Split Merge image segmentation method, including three m files, predict is the splitting and merging rule code, split_ Test is used to detect whether splitting is needed, and splitmerge is used for splitting and merging)

萤火虫算法的源代码，函数文件，可直接运行，用来寻找图像阈值分割的最优值（三阈值）。(firefly algorithm function.)

陷波滤波器，可调节陷波频域位置，可调节陷波大小，函数，可直接调用，由高斯，理想，巴特沃斯组成。(notchfilter, which is suitable for digital image processing in frequency domain. Notch filter, adjustable notch frequency domain position, adjustable notch size, function, can be called directly, composed of Gauss, ideal, Butterworth.)

包滤波器，主要功能是在给定的滑动窗口大小下，对每个窗口内的像素值进行相加求和(Packet filter, the main function is given under the sliding window size for each window of the pixel values ​ ​ summed)

本文献讲述了使用多维的结构张量进行基于分水岭的图像增强和去噪方法(The literature describes the use of multi-dimensional structure of tensor-based watershed image enhancement and denoising)
