Key-frames extraction technology for motion capture data can extract some important frames which describe the original motion sequence well, it is useful in motion retrieval, compression and edition. In this paper, we propose a new method for extracting key frames from motion capture sequence based on asynchronous learning factor PSO (Particle Swarm Optimization). Our proposed approach consists of...
In this paper, operators are encapsulated by services in algorithms for large-scale optimization problems and the services are deployed in distributed systems. Response time is an important factor for the performance of cooperative services. The message parse time is analyzed. Initial service accessing time is the main overhead for service calling. To decrease both the initial time and the response...
Color-to-gray is a classical manipulation in image processing. In this paper, a kernel based method is presented to carry out color-to-gray operation. It is noticeable that, in a meaningful color image only the linear combination of the three color components of every pixel is hardly enough to describe the implication relation between the luminance and chrominance in every pixel, or between pixels...
