另存为一个新的BMP文件，要求显示出原BMP图像和新BMP图像。 2．编程实现图像傅立叶高通、低通滤波。 3.打开一幅图像，添加椒盐、高斯噪声，然后使用邻域平均法、中值滤波法、K邻近平均法进行平滑 4.打开一幅图像，利用Roberts梯度法、Sobel算子和拉普拉斯算子进行锐化，并比较结果。 5.编写一个程序，对输入的图像进行哈夫曼编码，显示原图像的熵、编码后的平均码字长度、并能够根据编码重建出图像 6.在图像中生成一个矩形，然后用模板匹配法找出矩形位置。使用SSDA或改进的SSDA法-ave as a new BMP file to show the original BMP image and new BMP images. 2. The programming to realize image Fourier high-pass and low-pass filtering. 3. Open an image, add salt and pepper, gaussian noise, and then use the neighborhood averaging method, median filtering, K neighborhood average method for smoothing 4. Open an image, using the method of the Roberts gradient, Sobel operator and Laplacian sharpening, and compare the results. 5. Write a program to input image Huffman encoding, and display of original image entropy, encoded average code word length, and can according to the code 6.
