representations by listing all possible solutions. The automatic reconstruction of 3D objects from Several others have followed their approach and their 2D projections is briefly reviewed. Many algo-developed algorithms that can reconstruct planar rithms have been published to tackle this problem in faced 3D objects. Gujar and Nagendrah gave a(More)
When a Voronoi diagram is constructed incrementally, the quaternary-tree bucketing method of Ohya et. al. provides a useful way of spreading out the insertion order of the generator sites and obtaining initial guesses for the place to insertion them. This reduces the average time complexity of constructing Voronoi diagrams for n generator sites from O(n 2)(More)
INTRODUCTION Cement pressurisation is important for the insertion of both the acetabular and femoral components during Total Hip Arthroplasty (THA). Secondary to pressurization the rare phenomenon of unilateral cement incursion into the nutrient foramen has previously been reported. No bilateral case has been reported to date. This has implications both for(More)
—Multimedia services are the cornerstone of the Next Generation Network (NGN) architectures and judging by the success of video services in the Internet, future multimedia applications will be heavily video dependent. Due to the heterogeneous nature of the access networks and the range of end terminal devices that will connect with NGNs, video services will(More)
We show how scanned images can be segmented on the basis of their stochastic nature without a priori knowledge of the number of regions or their model parameters. The region distribution is modelled by a Mesh Markov Random Field while each region is filled with textures modelled by a Binomial Markov Random Field (BMRF). A hierarchical fuzzy clustering(More)
