红外图像序列动态帧间滤波技术

Dynamic Inter-frame Filtering in IR Image Sequences

该文提出了红外图像序列的动态帧间滤波技术 ,把图像序列作为二维数据流 ,采用先进先出的方式在整个积分周期内进行多帧平均 ,实现了沿着运动轨迹进行帧间滤波。对于活动红外图像序列 ,该技术能够有效地抑制噪声、提高信噪比 ,也能够降低运动目标的模糊程度。

In this paper, the dynamic inter-frame filtering enhancement technique is presented. In this approach, the infrared image sequences, as two-dimension data stream, using FIFO, have multi-frame averaging in the whole integral cycle. The inter-frame filtering along motion trace is realized. Therefore, using this technique in active image sequence, the satisfied results of suppressing noise and improving signal-to-noise rate can be obtained and the blur degree of moving target may be reduced.
