RdwtSvdWatermarking
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.)

背景差分法运动目标检测,建立背景模型,然后使用当前模型与背景模型相减,再和阈值相比较,比阈值大的即判断为有运动目标,比阈值小的即判断为没有运动目标,阈值大小可以自己适当调试,根据经验值设置最佳阈值。(Background difference method is used for moving target detection and setting up background model, then using current model and background model subtracting, and comparing with threshold, it is judged to have moving target compared with the threshold value, which is smaller than threshold. The size of threshold can be adjusted properly, and the best threshold is set according to experience value.)
