as-relief is intended for 2D to 3D conversion using the depth map.
The application opens two images: one is a coloured flat image, the other is its depth map, which shows us what areas are closer to us, and what are more distant. The white area is located at the foreground, the black one is at the background. Thereby, the general task is the acceptable depth map creating.
Application creates the Anaglyph image, ViewMaster, Cross Eyed, several viewpoints for lenticular image, ChromaDepth image (you need ChromaDepth glasses to See This images - www.chromatek.com). There is Batch processing too.
