Abstract
The thickening and its dual operation, the thinning, are fundamental transformations in image analysis. These operations are defined in any dimensional space. A fast algorithm is presented here, allowing a three dimensional thickening of a digitized image preserving its connectivity.
Keywords : Euler-Poincaré characteristic, mathematical morphology, thickening
