| 摘 要： | 利用自然背景与人造目标在分形维数上的差异,提出了一种针对自然背景下的快速红外目标检测技术。通过对图像各个子图的改进不规则分形维数的计算,得到各个子图的指标函数J曲线;经过对J曲线的适当策略分析,可以得到目标最大可能存在的子图区域,或者多目标可能存在的区域。仿真实验证明:算法可以快速检测出红外图像中人造目标可能出现的区域,为随后的识别跟踪等分析降低了计算量。

| Abstract: | A fast detection algorithm for artificial IR targets is presented which is based on the difference of fractal dimensions between simple natural background and man-made targets.By the calculation of the fractal dimension of each sub-image,the J plot of sub-images is made as a goal function.Under the analysis of some preference strategy for J plot,the most possible areas with targets are recommended.The experiment results show that the artificial targets could be quickly detected in maximum possibility,the calculations are reduced in the subsequence recognition analysis. |
