In this paper, an improved method is proposed based on AntTree clustering algorithm to deal with MRI image. This algorithm uses a new tree-structure model to accelerate the calculation and combines greedy algorithm to update the cluster centre. Compared with K-means and FCM algorithms, the results in the experiment show that the improved AntTree clustering algorithm is a better method in image segmentation...
Tracking moving objects in video sequences requires a robust technique. In this paper, a novel object tracking method is discussed. The color distributions histograms is integrated into particle filter, which is also considered the target??s shape as a necessary factor in target model. To compare the target model with the current hypotheses of the particle filter, the Bhattacharyya coefficient is...
