Paper Abstract

We propose a 3D edge detector for 3D gray voxel-based data, generalizing the well known Sobel operator for 2D images. Three differentiation operators are defined corresponding to the three principal directions (coordinate axes). Each operator computes the sum of the intensity differences between certain pairs of neighbors of a voxel corresponding to a principal direction. The proposed edge detector corresponds to the square root of the average of the squares of the three differentiation operators. Implementation of the proposed operator is given for biological images.
