Abstract
The invention relates to the field of binary image processing operations, such as thinning or thickening of 2D or 3D images with pixels or with voxels, respectively. The device according to the invention has processing means which rely on the logic of binary decision diagrams, of reduced order and with inverting branch instructions, in particular for determining whether or not a current element is a simple point. The binary decision diagram then defines a set of comparisons of bits of the elements of a chosen neighbourhood of the current element, which ends up at a terminal node “1” or a terminal node “0”, defining a particular property of the current element.
