X光序列图像三维动态滤波技术

对于静态X光图像序列，帧间滤波技术是抑制噪声、提高信噪比最为有效的方法之一。然而对于活动图像序列，该技术会使运动目标模糊，从而使图像质量更差。本文提出了一种X光序列图像的三维动态滤波技术，把图像序列作为二维空间数据流，在时间上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，从而使多帧平均技术对于活动X光图像序列同样具有较好的处理效果。

3-D Dynamic Filtering in X-ray Sequence Images

In static X ray sequence images, the inter frame filtering is the one of the best techniques of suppressing noise and improving signal to noise rate. But in active image sequence, the moving target may be fuzzy and the quality of image may be worse by using inter frame filtering. In this paper, the 3 D dynamic filtering enhancement technique is presented. In this approach, the X ray images 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, the satisfied results can be obtained in active X ray images sequence processing.
