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)

图像压缩经典EZW算法 可提初学者学习参考使用(image compression EZW)

说明：  水平集图像分割方法的一个经典DEMO，05年CVPR上的文章的实现程序，无偿呈现(Level set image segmentation methods of a classical DEMO, 05 years CVPR articles realization procedures, free show)

图像巴特沃斯陷波器，实现了简单的巴特沃斯陷波器滤除图像的某些频率的干扰(Image Butterworth notch filter, to achieve a simple Butterworth notch filter to filter out images of certain frequency interference)

avi视频读取，与播放，并将图像的每一帧保存下来(avi video reads, plays with, and saves each frame of the image)

图像处理功能：求the MSE/SNR/PSNR and the quantized image( the MSE/SNR/PSNR and the quantized image)

说明：  多尺度加权的rentinex算法实现图像增强，里面用到了高斯滤波对图像进行滤波，可以去除大部分的噪声，平滑图像效果较突出，3个高斯尺度对图像做滤波后加权在一起得到多尺度信息的图像。(Multiscale weighted rentinex algorithm is used to enhance the image. Gauss filter is used to filter the image, which can remove most of the noise. The smoothing effect of the image is prominent. Three Gaussian scales are filtered and weighted together to get the multi-scale information of the image.)

基于模板匹配的另一种人脸识别的算法，很实用，利用肤色建模来建立人脸皮肤模型(Another based on template matching algorithm for face recognition, very practical, using skin color modeling to create a human face skin model)

利用matlab编程技术将灰度图像归一化到0-255范围内(Normalize the image to 0-255)

图象处理用于对BMP格式的图象进行几何校正.(image processing used to BMP format images geometric correction.)
