| Abstract: | The real-time detection algorithm of dim small moving target in cluttered cloud background image sequences is one of key algorithms in IR precise homing systems. This paper analyzes the image pixels in cluttered cloud background image sequences, two max order filters and adaptive variance filter suited for the point target detection from temporal profile of the image sequences, and then presents an algorithm suited for the small target in the cloud image sequences. With the result of real image data experiments, it can be pointed out that it is a simple, less memory, parallelizable and real time algorithm. Finally based on the analysis of the experiment results, we point out the future work. |
