| 摘 要： | 在选择掩模平滑算法中,需要计算一幅图像的大量局部窗口的灰度均值和方差。而运用积分图像和平方积分图像,可以实现一种计算速度与图像窗口大小无关的灰度均值和方差的快速计算方法。将这种灰度均值和方差的快速计算方法运用于选择掩模平滑算法中,来计算各个掩模的灰度均值和方差,能够大大地提高算法的计算速度,从而实现了选择掩模平滑算法的快速计算。

| Abstract: | In selective masking smoothing algorithm,it is needed to calculate grayscale average and variance of a large number of image windows.Integral image and square integral image can be used to realize a rapid algorithm for calculating grayscale av-erage and variance of image windows,and the calculating speed is independent of the windows'size.Using this rapid algorithm to calculate grayscale average and variance of each masking can improve the computing speed of selective masking smoothing algo-rithm,hence the ... |
