As part of ITS technology, to achieve quick map updates, we propose a method for automatically detecting changes in streetscapes from images captured by car-mounted omni-directional cameras. It comprises two stages; accurate alignment of a map and street images taken at various times, and detection of changes in streetscapes from the aligned data. The(More)
We have developed a hi ghly parallel and accelerated circuit simulator which produces precise results for large scale simulation. We incorporated multithreading in both the model and matrix calculations to achieve not only a factor of 10 acceleration compared to the defacto standard circuit simulator used worldwide, but also equal or exceed the performance(More)
