matlab均方偏差MSD

matlab中的均方偏差(Mean Squared Deviation, MSD)是一种用于衡量两幅图像之间差异的算法。它的计算公式为D=1W∗H∑x=1W∑y=1H[S(x,y)−T(x,y)]2 ，其中S(x,y)表示原始图像在坐标(x,y)的像素值，T(x,y)为待评价图像在坐标(x,y)的像素值，W和H分别代表图像的宽度和高度。MSD是指图像之间每个像素值的差的平方和的平均值。其值越小，表示两幅图像的相似度越高。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
