This thesis proposes a Chamfer-based method for human body pose detection that combines silhouette matching, motion information, and statistical relevance estimates in an original way. We demonstrate that our method can not only detect people but also recover their full 3D pose when they are seen from different viewpoints and at different scales, when the background is cluttered and background ...

The use of hierarchical Chamfer Matching (CM) to match die patterns on VLSI wafers for the alignment of semiconductor chips is presented. This method can extract images with non-umform lighting (without loss) for matching, and somehow it is invariant to some environment changes. Here, it is applied to align IC patterns under non-uniform lighting while the normalized correlation method fails. Ex...

The first solution for addressing this new wire bonding challenge was the matte finish. Along with some geometrical capillary tip modifications, such as the double internal chamfer (IC), these changes proved Cu wire to be a reliable substitute to gold (Au). However, while the welding requirements were achieved, the tool’s resistance to wear deteriorated. This was expected as the hardness of Cu ...

The intramedullary alignment guides used in total knee replacement disrupt the intramedullary vessels, resulting in greater postoperative blood loss. The use of an autologous bone plug to seal the intramedullary femoral canal has been shown to be effective in reducing postoperative bleeding. The authors present a simple technique to create a bone plug from the anterior chamfer femoral cut to pe...

Image matching is an important task. There are many available methods for occluded image matching, e.g. Hausdorff distance, Distance Transformi and wavelet decomposition based methods. We proposed Modified Chamfer Matching Algorithm (MCMA) [16], a new simple distance transform based image matching algorithm. Here we propose few more matching measures and compare them. Basic concepts relating to...

This paper describes a novel image registration method for movement correction of fMR time-series. It is important to align the fMR images in the time-series before time-dependent analyses. This registration method aligns the boundaries of brains extracted from the functional images. It uses a genetic algorithm to minimize the distance function obtained from the chamfer distance transform. The ...

By propagating a vector for each pixel, we show that nearly Euclidean distance maps can be produced quickly by a region growing algorithm using hierarchical queues. Properties of the propagation scheme are used to detect potentially erroneous pixels and correct them by using larger neighbourhoods, without significantly affecting the computation time. Thus, Euclidean distance maps are produced i...

OBJECTIVES To investigate if general dental practitioners (GDPs) in private practice in Jordan follow universal guidelines for preparation of anterior teeth for resin bonded all-ceramic crowns (RBCs). MATERIAL AND METHODS A sample (n=100) of laboratory models containing 208 tooth preparations for IPS Empress and In Ceram, featuring work from different GDPs, was obtained from 8 commercial dent...
