Abstract: Fast and accurate 3D object reconstruction and partial 3D component retrieval from 2D image slices represent a difficult and challenging problem. To group related objects on different layers in an image stack, image segmentation and sequential matching of adjacent 2D objects have to be preformed. Object matching involves heavy computing and is time consuming. In this paper, we propose a new approach for parallel implementation of object contour matching and partial 3D component retrieval based on image contour structure. The method has been implemented in MPI on a SGI Origin 2000 machine. The experimental results show a good speedup for sequential object matching and partial 3D component retrieval.

Keywords: neuron confocal images; parallel processing; image contour matching; edge detection; feature detection; fuzzy object matching; 3D component retrieval; object reconstruction; bioinformatics; bio-images; database retrieval; biological structures.
