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.
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。
then using molecular sieve, frame filtering for refining to remove trace of water and miscellaneous machine, which make the products are transparent and bright.
