median_image can be used, for example, to smooth images, to suppress unwanted objects (e.g., point-like or line-like structures) that are smaller than the mask, and can therefore be used to estimate the background illumination for a shading correction or as a preprocessing step for the ...
median_imageuses an algorithm with a runtime per pixel that depends on the mask height 2 *Radius+ 1. Therefore,median_imageis slower thanmedian_rectfor square masks with a large mask height. The precise mask height for whichmedian_rectwill become faster thanmedian_imagedepends on the computer...
*median_image(Image : ImageMedian : MaskType, Radius, Margin : ) *功能:中值滤波。 *median_image使用一个正方形或圆形的掩码对输入的图像进行中值滤波,滤波结果返回到ImageMedian中。 * 可以使用MaskType选择掩码的形状。 可以使用“Radius”选择掩码的半径 ...

median() Reduces an image collection by calculating the median of all values at each pixel across the stack of all matching bands. Bands are matched by name. 通过计算所有匹配波段堆栈中每个像素处所有值的中位数来聚合图像集合。乐队按名称匹配。
Filter that finds the median value of each channel for pixels in the region around each source image pixel.

In order to select an optimal threshold for image thresholding that is relatively robust to the presence of skew and heavy-tailed class-conditional distributions, we propose two median-based approaches: one is an extension of Otsu's method and the other is an extension of Kittler and Illingworth...
