DeAnaglyph

Introduction

DeAnaglyph is a software to reconstruct the right view of a stereo image from the left view and a color anaglyph image. It is supposed to convert anaglyph movie DVDs, which usually offer both a 2D and a 3D version (e.g. Shrek 3D and Spy Kids 3D PAL editions), to stereo pairs for shutterglasses viewing or passive projection. However, the algorithm is not fast enough to convert movies yet. It takes a few minutes to convert a single frame. :-(

Click here to download version 0.1 together with the first two sample images shown on this page. Please note that the horizontal parallax must be within ±20 pixel and the vertical parallax within ±5, else the algorithm will produce artefacts. Only pixels within a 16 pixel wide border can be processed. This limitations will be removed in future versions. The input anaglyph image must be a color anaglyph image without any optimizations.

This is an alpha release to demonstrate the capabilities of the algorithm to interested people. It is not recommended to use it to actually convert movies, since quality and speed are still low and will (hopefully) improve in next versions!

Sample 3

This sample was taken from the Mission 3D - Game Over (Spy Kids 3D) PAL DVD. Due to the MPEG compression, the anaglyph quality is much lower than in the previous samples and it seems that slight color corrections were done. For this reasons, the output quality is lower than in sample 1 and 2. In addition, the large background areas hidden by agent Juni are difficult to reconstruct.
