1)  adaptive threshold filtering
自适应门限滤波
1.
On the basis of the analysis of an infrared scene model,a frame detection method which uses the adaptive threshold filtering to restrain background and uses the adaptive threshold segmentation to segment targets is proposed against the signatures of the small weak infrared moving targets in air infrared images.
在分析红外场景模型的基础上,针对空中红外图像中弱小运动目标的特征,提出一种用自适应门限滤波对背景进行抑制、利用自适应阈值分割对目标进行分割的帧内处理方法;在帧间采用八邻域判决法对弱小目标进行检测;实践证明,该技术能有效提高图像的信噪比,从而达到有效分割和快速检测小目标的目的。

补充资料:自适应卡尔曼滤波
分子式:
CAS号:

性质:在利用测量数据进行滤波的同时,不断地由滤波本身去判断系统的动态是否有变化,对模型参数和噪声统计特性进行估计和修正,以改进滤波设计,缩小滤波的实际误差。此种滤波方法将系统辨识与滤波估计有机地结合为一体。
