matlab的图像处理。图像编码（HUFFMAN编码）小波变换，1、 分别用sobel、Laplacian-Gaussian方法对一幅灰度图像进行边缘提取-Matlab image processing. Image Coding (HUFFMAN coding) wavelet transform, 1, respectively segmentation, Laplacian - Gaussian approach to a gray-scale image from the edge

导入一幅含有交通标志的图像，可以对该图像添加高斯、椒盐等噪声并进行中值滤波、维纳滤波、小波去噪等，最终目的可以实现对图像的RGB、HSV以及SVF的颜色分割。-Importing a traffic sign containing the image, you can add a Gaussian, salt and pepper and other noise on the image and median filtering, Wiener filtering, wavelet de-noi
