3D LoG Sharpening

Original Filtered
We have developed a 3D shape measurement method of opaque objects. We removed the shadow and the specular reflection using the principal component analysis, estimated the light source direction using the singular value decomposition, and estimated the surface normal of the object using the photometric stereo. Shadow and specular reflection are removed by iteratively computing the principal component analysis. Light source direction is estimated from the images and the shape obtained by 3D laser range sensor.
