An automatic procedure for extracting topological features, like protrusions or depressions, through holes or handles, from a relational boundary model of a solid object, called edge-face graph, is described. The recognition method is based on testing the node connectivity properties of the edge-face graph and defines a multilevel decomposition of the graph model.

The investigation of the three dimensional nature of our physical world makes necessary the acquisition of a three dimensional volume of data, from which it is possible to extract, with some linear or non linear processing, the information sought. In this presentation, we will examine different technologies for the extraction of the three dimensional structure from the combination of different views.

This paper attempts to describe the important characteristics of a distributed computing environment for patternrecognition. A multiprocessor-based system that has some of these characteristics is then proposed for the analysis and possible implementation of various image transforms. Algorithms have been developed to allow the direct computation of 2-d Fourier, Walsh and Hadamard transforms in a ″distributed″ manner.

pattern spotting consists of retrieving the most similar graphical patterns from a collection of document images. Inspired by the recent advances in computer vision and word spotting techniques, we propose in this paper an unsupervised, segmentation-free pattern spotting system. Overall, the system includes a powerful patch-based framework, the bag of visual word model with an offline sliding window mechanism to avoid heavy computational burden during the retrieval process. Our system takes advantage of the most recent powerful compression and distance approximation techniques (product quantization and asymmetric distance computation) to efficiently index the great number of sub-windows produced by sliding windows and allows to retrieve small sized queries in a large indexed corpus.

A sequential procedure based on the use of the 4-distance transform is presented to find simultaneously both the endoskeleton and the exoskeleton of a digital figure. The main advantage of the proposed algorithm is that only four sequential raster scans of the picture are sufficient to accomplish the whole process.
