oxidctf
oxidctf is a Rust port of HolyWu/VapourSynth-DCTFilter / Mr-Z-2697/VapourSynth-DCTFilter, a VapourSynth plugin that suppresses selected frequencies of a clip. For each n x n block it performs a Discrete Cosine Transform (DCT), scales down the selected frequency values, and then reverses the process with an Inverse Discrete Cosine Transform (IDCT).
Install
pip install vapoursynth-oxidctf
API
oxidctf.DCTFilter(
clip: vs.VideoNode,
factors: Sequence[float],
nsize: int = 8,
planes: Sequence[int] = [0, 1, 2],
) -> vs.VideoNode
-
clip— Clip to process. Any format with either an integer sample type of 8-16 bit depth or a float sample type of 32 bit depth is supported. -
factors— Eithernsizeornsize * nsizefloating point numbers, all of which must be in the range0.0 <= x <= 1.0.With
nsizevalues, these correspond to scaling factors for the rows and columns of the n x n DCT blocks. The leftmost number corresponds to the top row, left column. This is the DC component of the transform and should always be left as1.0. The row and column numbers are multiplied together to get the scale factor for each of the values in a block.With
nsize * nsizevalues, they are used directly as a row-major per-coefficient scaling matrix, which allows patterns that the outer product cannot express. -
nsize— Size of the DCT blocks. -
planes— Which planes to process. Any unfiltered planes are copied from the input clip.
