| Abstract(in English) | This paper proposes an optimal matching algorithm which performs segmentation-free matching between two time-space patterns. One of the two time-space patterns is a pixel trajectory called a reference time-space pattern with a fixed time interval and composed of a sequence of two-dimensional location parameter. The other one is called an input time-space pattern composed of an endless stream of image frame of gray level pixel. The proposed algorithm automatically detects a time-space pattern with a fixed time interval from an input time-space pattern without segmentation. The detected pattern is optimally similar to the reference pattern. The similarity value is optimally determined by the proposed algorithm based on dynamic programming. Recognition of a reference pattern is carried out at each time by detecting a minimum value of two-dimensional pattern composed of accumulated minimum distance values. Shape of moving object is detected by pixels with similar movement. Tracking is also realized by concatenating spotting results of primitive reference patterns. |
