20100166260 | METHOD FOR AUTOMATIC DETECTION AND TRACKING OF MULTIPLE TARGETS WITH MULTIPLE CAMERAS AND SYSTEM THEREFOR - A method for automatically detecting and tracking multiple targets in a multi-camera surveillance zone and system thereof. In each camera view of the system only a simple object detection algorithm is needed. The detection results from multiple cameras are fused into a posterior distribution, named TDP, based on the Bayesian rule.

To properly handle the tracking of multiple moving targets with time, a sample-based framework which combines Markov Chain Monte carlo (MCMC), Sequential Monte Carlo (SMC), and Mean-Shift Clustering, is provided. The detection and tracking accuracy is evaluated by both synthesized videos and real videos. The experimental results show that this method and system can accurately track a varying number of targets. | 2010-07-01 |

After calibration, a 3D (stereo) sensor system views the object to derive a runtime 3D representation of the scene containing the object. Rectified images from each stereo head are preprocessed to enhance their edge features. A stereo matching process is then performed on at least two (a pair) of the rectified preprocessed images at a time by locating a predetermined feature on a first image and then locating the same feature in the other image. 3D points are computed for each pair of cameras to derive a 3D point cloud. The 3D point cloud is generated by transforming the 3D points of each camera pair into the world 3D space from the world calibration. The amount of 3D data from the point cloud is reduced by extracting higher-level geometric shapes (HLGS), such as line segments. Found HLGS from runtime are corresponded to HLGS on the model to produce candidate 3D poses. A coarse scoring process prunes the number of poses. The remaining candidate poses are then subjected to a further more-refined scoring process. These surviving candidate poses are then verified by, for example, fitting found 3D or 2D points of the candidate poses to a larger set of corresponding three-dimensional or two-dimensional model points, whereby the closest match is the best refined three-dimensional pose. | 2010-07-01 |

20100166359 | OPTICAL WAVEGUIDE MODE SENSOR HAVING PORES - A chip is constituted from a transparent substrate, a reflector film formed on the transparent substrate and an optical waveguide layer formed on the reflector film, and a plurality of pores is formed in the optical waveguide layer. A light-introducing mechanism that introduces light from the transparent substrate of the chip onto the reflector film, and a light-detecting mechanism that detects the light reflected on the reflector film are provided. A specimen under investigation is detected by sensing a change in the incidence angle or in the intensity of reflected light that occurs when the specimen is adsorbed or deposits on the surface of the optical waveguide layer, by using a range of incidence angles of the light in which the intensity of reflected light changes when a part or all of the incident light couples with the optical waveguide mode that propagates in the optical waveguide layer. | 2010-07-01 |
