一个关于数字图像处理的PPT教程,希望对大家有所帮助(On digital image processing PPT tutorials, and they hope to help everyone)

说明：  提供激光雷达点云数据的读取，滤波及分类功能(LIDAR point cloud data available to read, filter and sorting functions)

说明：  数字图像处理中非常有用的一些图片包括LENA等.(Digital image processing is very useful in a number of pictures, including LENA, BARBARA such.)

matlab实现灰度预测，很好的例子，有详细说明(Matlab to achieve grayscale prediction, a good example, with detailed instructions)

冲击滤波模型是用用于图像边缘增强的一种常用算法(Impact filtering model is a commonly used algorithm for image edge enhancement)

香港浸会大学吴国宝的快速TV（total variation）的处理程序，可以运行，结果良好。(David Ng Hong Kong Baptist University Fast TV (total variation) of the process, you can run with good results.)

利用有限差分和MATLAB矩阵运算直接求解二维泊松方程(Directly solving the 2D Poisson equation using finite difference and MATLAB matrix operations)

该算法实现字母个数的统计,希望对大家有用!()

说明：  基于灰度共生矩阵的纹理特征提取方法实现目标的识别(Gray-level co-occurrence matrix based texture feature extraction methods to achieve the target identification)

首先对指纹图像进行预处理，包括图像的分割，增强，二值化，细化。对细化后的图像进行特征点的提取，最后通过细节特征匹配完成指纹的识别。(Firstly, the fingerprint image is preprocessed, including image segmentation, enhancement, binarization and thinning. The refined image is extracted by feature points, and the fingerprint recognition is completed by minutiae feature matching.)
