基于FPGA的序列图像能量累加

低信噪比小目标检测是当前的研究热点,能量积累是其关键技术之一。介绍了两种常用的序列图像能量累加算法：一种是针对帧间运动速度较小的多帧累加；一种是针对帧间运动速度较大的形态膨胀累加。并给出了这两种算法的FPGA实现。实验结果表明,设计的电路运行速度快、占用资源少,具有很强的实用性,并在实际应用中取得了较好的效果。

Energy Accumulation of Image Sequences Based on FPGA

Low SNR point target detection is the currently research focus,energy accumulation is one of its key elements.Two fre- quently used image sequences energy accumulation algorithm are discussed.One is muti-frames cumulating aim at slow moving targets, the other is morphological dilation-cumulating aim at fast moving targets.The FPGA implementation of these two algorithm are presented. Experiment shows the implementation has simple structure,clear flow,high running frequency,less periphery components,good expansi- bility,portability,and have been successfully applied in IR information processor.
