| Abstract: | The automatic detection of dim infrared target with low Signal Noise Ratio(SNR) under complicated background is a difficult problem to be resolved.In study of the problem,we proposed a target detection algorithm based on median subtraction filter and multi-grad search algorithm.Firstly,the dim target was separated from infrared background by using median filter.Then,the real target was extracted by using multi-grad search algorithm.Finally,morphology-based algorithm was used to fill the inner space of targe... |
