一种基于差帧图像融合的弱小目标增强方法

A Weak and Small Target Enhancement Method Based on Image Fusion

为了能够在小目标检测时更加容易和准确的检测出弱小目标,提出了一种基于差帧图像融合的弱小目标增强算法,该方法首先对视频相邻帧进行差帧处理,然后对差帧结果进行图像融合,最后把融合结果与原视频帧图像的低频分量进行差分运算获得增强图像。实验结果表明该方法的正确性,实现了对弱小目标的有效增强。

For easily and accurately detecting weak and small target in small target detection, a weak and small target enhancement method was proposed based on difference-frame and image fusion. Firstly, the difference-frame operation was performed on adjacent frame images. Secondly. the image fusion was conducted for the result of the difference-frame operation. Finally, the enhanced images were obtained through difference operation between the fusion result and low frequency of the source image. The experiment results show that the method is correct and can enhance weak and small targets effectively.
