针对红外运动弱小目标检测中单帧图像检测率低的问题,在分析了红外图像中运动弱小目标特性的基础上,提出了一种基于序列图像分组决策检测红外弱小目标的方法.该方法利用图像差分法进行目标信息的提取,对图像进行扩边,选取连通域质心来构建滑动邻域块,最后充分利用目标航迹的连续性和噪声的随机分布特性进行目标位置的决策.实验证明,序列图像检测方法对红外弱小目标的检测率要高于单帧图像检测率.
針對紅外運動弱小目標檢測中單幀圖像檢測率低的問題,在分析瞭紅外圖像中運動弱小目標特性的基礎上,提齣瞭一種基于序列圖像分組決策檢測紅外弱小目標的方法.該方法利用圖像差分法進行目標信息的提取,對圖像進行擴邊,選取連通域質心來構建滑動鄰域塊,最後充分利用目標航跡的連續性和譟聲的隨機分佈特性進行目標位置的決策.實驗證明,序列圖像檢測方法對紅外弱小目標的檢測率要高于單幀圖像檢測率.

@@@@According to the problem of low detection rate for single frame image during the small moving in?frared target detection process, on the basis of analyzing the characteristics of infrared images of small moving tar?gets, a method for detecting small infrared targets based on sequence image grouped decision is put forward. Image difference method is used to extract target information. Edges of images are expanded and centroid of connected do?mains is chosen to construct sliding neighborhood blocks. Decisions of target positions are made by making full use of continuity of target tracks and random distribution characteristics of noise finally. The experiments prove that the detection method of sequence image has a higher detection rate than that of single frame image detection method.
