摘要
文章基于一种用于红外图像小目标检测的多级滤波算法,提出其硬件实现结构。该结构选用统一的1×3模板,通过改变滤波器的级连数目得到不同大小的滤波模板,从而检测不同大小的小目标。数据路径包含三个并行的数据通道,采用流水线形式对数据进行处理,分别检测1×1~1×3、1×4~1×5和1×6~1×7的目标。这种结构可以对输入的红外图像进行实时处理。
This paper analyzes the characteristics of the small target, background and noise of sea surface's infrared images respectively and a mathematic model is educed to examine the small targets. Then we propose a hardware structure to meet the need of the algorithm. With uniform 1×3 templet the structure can examine different of targets by changing the cascade number of the templet. The structure has three pathway to process the images, and during the every pathway pipeline technology is used. This structure can perform a real-time process to the input infrared images with the good effect.
