本代码是使用matlab编写的harr特征的代码，值得大家研究和参考(This code is the use of matlab prepared harr characteristics of the code, it is worth study and reference)

大牛人的图象恢复代码．全变分离散化的方法．经典中的经典．(Daniudi people to restore the image code. BCH-wide variable separation method. Classic classic.)

说明：  利用遥感做变化检测的时候可以用到的数据。(Data Used in Change Detection Using Remote Sensing)

FISM——结构相似度，它的功能为评价图像去噪效果，值越接近1，去噪结果越好。(FISM-- structural similarity, it functions is for the evaluation of image denoising effect, closer the value is to 1, better is the denoising results.)

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.)

说明：  可以检测行人和车辆，MATLAB的版本是R2017b，(It can detect pedestrians and vehicles. The version of MATLAB is r2017b)

说明：  MATLAB中cell转换为csv，用matlab语言实现(MATLAB cell to csv,matlab)

利用梯度算法--最快下降梯度算法进行图像的边缘检测(Gradient algorithm- the fastest decline in the gradient algorithm for image edge detection)

说明：  针对散焦图像编写的复原程序，复原效果不错，会产生振铃效应！(For the preparation of defocused image restoration program recover good results, will produce ringing effects!)

灰度双线性插值，缩放图像。可以对图像进行几乎无损的小倍数放大，倍数大时有损。(Gray bilinear interpolation, zooming the image. Can be almost non-destructive image to enlarge small multiples, multiples of large detrimental.)
