Photo-consistency explained

In computer vision, photo-consistency determines whether a given voxel is occupied. A voxel is considered to be photo consistent when its color appears to be similar to all the cameras that can see it.^[1] Most voxel coloring or space carving techniques require using photo consistency as a check condition in Image-based modeling and rendering applications.

Usage

3D Volumetric Reconstruction.^[2]

• Image registration.^[3]
• Multi-view reconstruction.^[4]
