Eedi3

Revision as of 23:17, 1 November 2014

Description

eedi3 (enhanced edge directed interpolation 3) works by finding the best non-decreasing (non-crossing) warping between two lines by minimizing a cost functional. The cost is based on neighborhood similarity (favor connecting regions that look similar), the vertical difference created by the interpolated values (favor small differences), the interpolation directions (favor short connections vs long), and the change in interpolation direction from pixel to pixel (favor small changes).

Requirements

• AviSynth 2.5.8 or later
• Supported color formats: RGB24, YUY2, YV12

** Note: eedi3 is threaded using OpenMP, and is compiled with Visual Studio 2012.
** Therefore, it needs the Microsoft Visual C++ 2012 Redistributable Package (vcredist_x86.exe) to be installed (for vcomp.dll).

Version      Date            Changes

v0.9.2       11/11/2013      - Changes by cretindesalpes
                             - SSE/SSE2 optimizations, giving a nice 4× speedup.
                             - Added an optional mask to process only the specified parts.
                               It’s helpful when EEDI3 is used as an anti-aliasing processor on cartoon-like materials. 
                               Additional 1.2×–2× speedup, depending on the source.
                             - I fixed a typo in the original code too, but I don’t know if it has any visible effect.
                             - Be sure to have Visual C++ Redistributable for Visual Studio 2012 installed (needed for vcomp11.dll).

v0.9.1       07/23/2010      - fix field=0/1 flipped with RGB24 input
                             - fix possible reading off the edge of a frame with cost3=true
