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.

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
