Copyright:
The MPSImageMedian applies a median filter to an image. A median filter finds the median color value for each channel within a kernelDiameter x kernelDiameter window surrounding the pixel of interest. It is a common means of noise reduction and also as a smoothing filter with edge preserving qualities.
NOTE: The MPSImageMedian filter currently only supports images with <= 8 bits/channel.
NSSecureCoding compatability While the standard NSSecureCoding/NSCoding method -initWithCoder: should work, since the file can't know which device your data is allocated on, we have to guess and may guess incorrectly. To avoid that problem, use initWithCoder:device instead.
Parameters:
Returns:
Reimplemented from MPSUnaryImageKernel.
Standard init with default properties per filter type
Parameters:
Returns:
Reimplemented from MPSUnaryImageKernel.
Initialize a filter for a particular kernel size and device
Parameters:
Returns:
The maximum diameter in pixels of the filter window supported by the median filter.
The minimum diameter in pixels of the filter window supported by the median filter.
The diameter in pixels of the filter window. The median filter is applied to a kernelDiameter x kernelDiameter window of pixels centered on the corresponding source pixel for each destination pixel. The kernel diameter must be an odd number.
