    说明:  1.使用medfilt2函数对‘lena.bmp’进行不同模板大小的中值滤波,并观察效果 2.使用fspecial函数构造‘gaussian’, ‘sobel’, ‘prewitt’, ‘laplacian’, ‘average’等不同滤波算子,使用filter2函数对‘cameraman.tif ’进行滤波,观察不同滤波器的效果 3.设计频域理想低通和理想高通滤波器,对‘phantom.bmp’图像进行频域滤波,显示滤波结果。然后改变截止频率,观察对结果的影响。 4.对‘homo.bmp’进行同态滤波,其中频域同态滤波器自行设计。要求在程序注释中说明你设计该滤波器的思想。(1' lena.bmp 'The median filtering with different template sizes was carried out and the effect was observed2. Fsspecial function is used to construct different filter operators such as' Gaussian ',' Sobel ',' Prewitt ',' Laplacian ',' average ', etc' cameraman.tif 'Filter and observe the effect of different filters3. Design ideal low pass and ideal high pass filters in frequency domain' phantom.bmp 'The image is filtered in frequency domain and the filtering result is displayed. Then change the cut-off frequency and observe the effect on the results.4. Yes' homo.bmp 'The homomorphic filter is designed by ourselves. The idea of designing the filter should be explained in the program notes.)

    将原始载体图片经过一维冗余离散小波变换分成四个子频带,分别对每个子频带进行奇异值分解, 将水印图片灰度值直接按比例缩小嵌入到奇异值矩阵中,再将此矩阵进行一次奇异值分解得到奇异值当做此子带的奇异值, 重建此子带矩阵,而后将进行反冗余离散小波变换得到嵌入载体后的水印图像。(The original image after the one-dimensional vector redundant discrete wavelet transform is divided into four subbands, respectively, of each sub-band for the singular value decomposition, the watermark image gray value scale down directly embedded into the matrix singular value, then this matrix is ​ ​ a Singular value decomposition singular value as the singular values ​ ​ of this sub-band, the reconstruction of this sub-band matrix and after anti-redundant discrete wavelet transform watermark image after embedding the carrier.)
