Description

nnedi3 is an intra-field only deinterlacer. It takes in a frame, throws away one field, and then interpolates the missing pixels using only

information from the kept field. It has samerate and double rate modes, and works with YV12, YUY2,and RGB24 input. nnedi3 is also

very good for enlarging images by powers of 2, and includes a function 'nnedi3_rpow2' for that purpose.

nnedi3 is nnedi2 with improved predictor neural network architecture and local neighborhood pre-processing. nnedi3 also has multiple

local neighborhood size options to better handle image enlargement vs deinterlacing and give more quality vs speed options.

Requirements:

- AviSynth 2.5.8 or later

- Supported color formats: RGB24, YUY2, YV12

Changelog

Version      Date            Changes

v0.9.4       06/10/2011      + some more optimizations + more aggressive new prescreener levels

v0.9.3       06/06/2011      + added new prescreener. Changed 'pscrn' parameter from bool to integer.
                             + added 'etype' parameter and merged abs/squared weights into one binary

v0.9.2       09/22/2010      + clean up and release source code
                             + speed improvements - (thanks Loren Merritt - akupenguin - for many ideas and code)
                                  int16 dot products in prescreener/predictor neural networks
                                  faster exp function approximation
                                  mean removal factored into weights
                                  lots of smaller changes
                             + new prediction nn weights for certain nsize/nns combinations
                             + added fapprox parameter
                             - fixed bug with border mirroring
                             - dropped support for sse/mmx - all asm code requires sse2. changed opt parameter
                                 accordingly.

v0.9.1       07/15/2010      + add nsize=5/6 (16x4,32x4)
                             + add nns=0 (16 neurons). nns 0/1/2/3 from v0.9 are now 1/2/3/4.
                             - new defaults. nnedi3: nsize=6,nns=1. nnedi3_rpow2: nns=3.
                             - fix field=0/1 flipped with rgb24 input

v0.9         06/10/2009      + First official release
                             - adds nns=0 (32 neurons). nns 0/1/2 from previous beta are now 1/2/3.
                             - adds nsize=4 (8x4).
                             - different nns/nsize defaults for nnedi3_rpow2() vs nnedi3()
                             - change setcachehints call
