3D Voxel Coloring



Voxel coloring is a technique used to create a photorealistic 3D scene reconstruction from a fairly sparse set of images without computing image correspondences.  It works by discretizing the 3D scene into small volume elements, called voxels, and reprojecting each voxel one-by-one back onto the image set.  Voxels that reproject onto a set of pixels with low color variance are colored accordingly, while voxels that reproject onto a set of pixels with high color variance remain uncolored.  A sweep of the entire scene volume yields a reconstruction of that scene.

The 3D voxel coloring algorithm available here is implemented in MATLAB.  The images below depict a 3D reconstruction it created from a set of 20 input images.
