| 摘 要： | 提出一种基于跳跃马尔可夫模型的红外点目标检测方法,根据模型设计了采用粒子滤器的模型参数与状态估计算法.该方法既能用于图像的空域滤波,也能用于序列图像的时域滤波.实验表明采用该方法进行空域/时域滤波可以极大地抑制杂波背景并增强点目标的可检测性.

| Abstract: | Spatial and temporal processing methods are the two basic algorithms for small targets detection in infrared images.Detection of infrared(IR) point targets is proposed,based on jump Markov model,and an algorithm for model parameter and state estimation was designed.The scheme can be applied to the temporal filtering in image sequences as well as to the spatial filtering in a single image.Experiments show that the approach can suppress clutter greatly and enhance the detectability of point targets at the same time when applied to spatial or temporal filtering. |

| Keywords: | point targets detection weighted median filter jump Markov model particle filter infrared image clutter suppression |
