| 摘 要： | 提出一种针对矩形窗口的图像中值滤波快速算法．它充分利用了相邻窗口间的相关信息，以中值为界将窗口内像素分成两组．当窗口右移一像素，根据当前分组和中值获得新窗口的分值，进而求出其中值．避免了现有算法对每一窗口进行排序取中的操作，降低了计算量

| Abstract: | fast algorithm for median-filtering of images using rectangular windows is proposed.This algorithm makes full use of the correlation information between neighbouring windows and divides the pixels inside the window intO two groups separated by the current median. Thecurrent median and groups can be used to form the groups for the new window, hence the new mediancan be obtained. The fast algorithm avoids the sorting operation for finding median, thus decreasesthe computation by a great deal. |
