[edit] Description
This is an adaptive Median Filter for eliminating certain types of noise. It uses local statistics (minimum, maximum and median values) of a moving local grid, and changes grid size depending on local statistics. Full Description
- For AviSynth+ see modPlus, includes high bit depth colorspace support and 64-bit.
[edit] Requirements
[edit] Syntax and Parameters
- AdaptiveMedian (clip, int "sf", int "ef", int "maxgrid", bool "yy", bool "uu", bool "vv")
- clip =
- Input clip.
- clip =
- int sf = 0
- Starting frame number to process.
- int sf = 0
- int ef =
- End frame number to process, default is the last frame.
- int ef =
- int maxgrid = 5
- Grid size to get statistics can grow to this value starting from 3x3.
- Range: 3 to 9
- Grid size to get statistics can grow to this value starting from 3x3.
- int maxgrid = 5
[edit] Examples
AdaptiveMedian with default values:
AviSource("blah.avi")
AdaptiveMedian(a, maxgrid=5, yy=true, uu=false, vv=false)
