Particle impoverishment, which always leads to accuracy decreasing, is a classical problem of the traditional particle filter resampling. A particle filter resampling method based on improved genetic algorithm is proposed in this paper to solve the problem. In the improved algorithm, a genetic resampling step is applied for particle reproduction. The main work of the improved algorithm include two...
The problem of tracking maneuvering point target in optical image sequence using a single sensor is considered in this paper. A morphology based method is proposed to pre-detect target area. This pre-detection begins with expansion of the target area by dilation using a selected rectangle structuring element. Then the target energy is enhanced by frame-addition. Finally, the target area is detected...
