Multitarget recognition algorithm based on conformability degree theory for multistage tracking process

In the paper, according to analyzing features of flight multi-targets in the far distance, a new multi-target recognition algorithm based on conformability degree principle for multistage searching process is introduced In the cursory searching period, all possible targets are quickly detected with the round template in the filtering binary image. After the cluster analysis for all possible targets based on distance conformability degree principle is finished, the centroid of all possible points in a same target is used as center of a local entropy region. In the precision searching period, the position of maximum entropy value of the local entropy region being labeled is gained to use as a growing seed for implementing region growing. In order to decrease operation amount and improve system real-time character, with entropy conformability degree principle, an improved region growing algorithm being combined simple linking algorithm with sub-region combination algorithm is used to rebuild image target
