以动态背景中红外运动目标为研究对象,针对二维初级运动检测器在时域上对运动敏感而引起目标运动矢量受背景变化干扰的问题,提出一种结合时域中生物视觉二维初级运动检测器和空域中区域生长方法的运动检测方法。该方法利用时域中二维初级运动检测器检测出运动矢量并将幅值最大的运动矢量作为区域生长的种子点,利用空域中运动目标具有较高红外辐射的图像特性,通过区域生长法,将热辐射特性强于背景的目标分割出来。仿真实验结果表明:该方法在去除背景干扰的同时提取出动态背景中的运动目标,与其他方法相比具有较高的信杂比。
以動態揹景中紅外運動目標為研究對象,針對二維初級運動檢測器在時域上對運動敏感而引起目標運動矢量受揹景變化榦擾的問題,提齣一種結閤時域中生物視覺二維初級運動檢測器和空域中區域生長方法的運動檢測方法。該方法利用時域中二維初級運動檢測器檢測齣運動矢量併將幅值最大的運動矢量作為區域生長的種子點,利用空域中運動目標具有較高紅外輻射的圖像特性,通過區域生長法,將熱輻射特性彊于揹景的目標分割齣來。倣真實驗結果錶明:該方法在去除揹景榦擾的同時提取齣動態揹景中的運動目標,與其他方法相比具有較高的信雜比。

An infrared moving object detection method which combines Reichardt-type two dimensions Elementary Motion Detectors inspired by biological vision and region growing method was proposed to solve the two dimensions EMDs′ sensitive problem in dynamic scenes. EMDs detected the most intensive motion vector signal in temporal domain which was then used as the seeds of the region growing. Region growing method was applied to make a segmentation of the target by its infrared radiation characteristic much different from background in spatial domain. The simulation illustrates that, combing the EMDs in temporal domain with the region growing method in spatial domain achieves much better detection performance in infrared frames than the original Reichardt′s model. Compared with other methods, the proposed method could achieve a higher SCR.
