DOT is a non-invasive imaging modality for visualizing and continuously monitoring tissue and blood oxygenation levels in brain and breast. The image reconstruction algorithm in DOT involves generating images by means of forward modeling results and the boundary measurements. The ability of the forward model to generate the corresponding data efficiently has a sign ificant role in DOT image reconstruction. FE technique using a fixed mesh is one of the most typical techniques for solving the diffusion equation in the DOT forward problem. However, in some medical applications, meshing task is difficult and the shape and size of elements make a further approximation in the forward problem. Mesh free Galerkin approach is also utilized in DO T, but imposing essential boundary conditions is difficult. In this paper, an approach based on combination of the two methods is used. The validity of the proposed method is investigated by simulation results.","PeriodicalId":91154,"journal":{"name":"Optomechatronic Technologies (ISOT), 2010 International Symposium on : 25-27 Oct. 2010 : [Toronto, ON].

Digital Speckle Pattern Interferometry (DSPI) and Digital Image Correlation (DIC) are two typical whole-field, non-contact experimental tech niques that allow rapid and highly accurate measurement of 3D-deformation and strain distributions with high resolution. The former can measure small deformation (in nanometric level) and can thus determine small strain (in micro strain level), the latter can measure relatively large deformation (micrometer and larger) and can thus determine large strain (from hundreds of micro-strain to considerable value). The combination of these two techniques covers from small to large ranges for whole field, non-contacting deformation and strain measurement, e.g. from nanometric level to a few millimeters or larger for deformation measurement and from micro strain to a few percents or larger for strain measurement. This paper reviews ESPI and DIC and their applications. Both potentials and limitation are listed. The challenges of these two techniques for real world applications are presented and analyzed.

Accurate information extraction from such data sets is a complex task due to the presence of multiple objects, diversity of their shapes, large disparity in the feature sizes, and the spatial uncertainty due to occluded regions. A fast segmentation of such data is necessary for quick understanding of the scanned scene. Unfortunately, traditional range segmentation methodologies are computationally expensive because they rely almost exclusively on shape parameters (normal, curvature) and are highly sensitive to small geometric distortions in the captured data. This paper introduces a quick and effective segmentation technique for large volumes of colorized range scans from unknown building interiors and labelling clusters of points that represent distinct surfaces and objects in the scene. Rather than computing geometric parameters, the proposed technique uses a robust Hue, Saturation and Value (HSV) color model as an effective means of id entifying rough clusters (objects) that are further refined by eliminating spurious and outlier points through region growth an d a fixed distance neighbors (FDNs) analysis. The results demonstrate that the proposed method is effective in identifying continuous clusters and can extract meaningful object clusters, even from geometrically similar regions.","PeriodicalId":91154,"journal":{"name":"Optomechatronic Technologies (ISOT), 2010 International Symposium on : 25-27 Oct. 2010 : [Toronto, ON].

Generally, to reduce the number of template pixels means low computational cost of matching. However, high-speed and high-reliability often have trade-off relation in actual situations. In order to realize reliable matching, it is important to extract few pixels that have unique characteristics about their location and intensity. For this purpose, analysis of co-occurrence histogram for local combination of multiple pixels is useful, because it provides beneficial information about simultaneous occurrence probability. In the proposed method, pixels with low co-occurrence probability are preferentially extracted as significant template pixels used for matching process. Also we propose a method to approximate n-pixels co-occurrence probability using some two-dimensional co-occurrence histograms to save memory space. Through some experiments using more than 480 test images, it has been proved that approximately 0.2 to 1% of template pixels extracted by proposed method can achieve practical performance. The recognition success rate is 96.6%, and the processing time is 15msec (by Core 2 Duo 3.16GHz).","PeriodicalId":91154,"journal":{"name":"Optomechatronic Technologies (ISOT), 2010 International Symposium on : 25-27 Oct. 2010 : [Toronto, ON].
