Description

This filter is designed to reverse the effects of bicubic upsampling. Parameters and sampling pattern try to mimic Avisynth's BicubicResize.

Requirements


Limitations

  • Sampling at 1:1 resolution is known to be unstable.
  • This filter is not made for upsampling.

debicubicY (clip, int target_width, int target_height, float "src_left", float "src_top", float "src_width", float "src_height", bool "lsb_inout", float "b", float "c")


clip   =

int  target_width =
int  target_height =
presumed 'native' resolution.


float  src_left = 0
float  src_top = 0
float  src_width =
float  src_height =
Optional crop rectangle in the input frame.
