基于地物分类真值的高光谱遥感图像分类精度评价(Accuracy uation of remote sensing image classification)

MATLAB可见水印、不可见水印添加程序源代码，可见水印部分采用中值法，不可见部分采用DWT变换。(MATLAB visible watermark, invisible watermark to add the source code, we can see the watermark part in value method, the invisible part on DWT.)

光线补偿 的matlab程序代码，有图片(Light compensation matlab code, pictures)

压缩感知的MRI算法实现,使用matlab,可以直接运行,压缩包内有图片(Compressed sensing MRI algorithm, using MATLAB, can be run directly, compressed packets have pictures.)

将一幅图像以jpeg的形式进行压缩，对初学者很有用(Jpeg form of an image compression, very useful for beginners)

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.)
