Real-time Failure Monitoring System for High Power IGBT Under Acceleration Test Up to 500 A Stress
Get PDF2014 IEEE 26th International Symposium on Power Semiconductor Devices & IC's (ISPSD), Jun 15-19, 2014, Hilton Waikoloa Village, Hawaii, USAReal-time failure monitoring system for IGBT module was demonstrated under 500 A power cycling test. The system successfully captured internal phenomena occurred in interface regions of the device under test. Moreover, we proposed realtime failure analysis method by combining the real-time monitoring and image processing techniques. This failure analysis method enables to distinguish the place where degradation occurs in DUT and also trace internal degradation process to failure
Multi-scale Analysis based Image Fusion
Get PDFThe 2nd International Conference on Intelligent Systems and Image Processing 2014 (ICISIP2014), September 26-29, 2014, Nishinippon Institute of Technology, Kitakyushu, JapanImage fusion provides a better view than that provided by any of the individual source images. The aim of multi-scale analysis is to find a kind of optimal representation for high dimensional information expression. Based on the nonlinear approximation, the principle and ways of image fusion are studied, and its development, current and future challenges are reviewed in this paper
New Vehicle Speed Measurement System with Image Processing
Get PDFThe 2nd International Conference on Intelligent Systems and Image Processing 2014 (ICISIP2014), September 26-29, 2014, Nishinippon Institute of Technology, Kitakyushu, JapanThis research proposes a new vehicle speed measuring system based on image processing technique. Generally, in order to detect the vehicle from image taken in dark circumstance, expensive high-performance camera is needed. However, this system needs only a cheap general camera, like digital camera or the camera mounted on smartphones. Thereby, this system uses as speed gun. By controlling the shutter speed of camera, a bright line which comes from the headlamp of a moving vehicle is appeared in the picture. Moreover, from even the image taken from the slant, the vehicle speed can be measured with a process of projective transformation. In this work, we developed an algorithm depend on this feature. Experiment result shows a reasonable measuring value
