The radiographic image noise often use a space domain filtering or a time domain filtering,these two methods have only considered the respective domain of pixels of the correlation among.It can achieve better effect than they used alone by combining the spatial filtering method with time filtering.It puts forward a noise reduction method of digital video with the combination of the intraframe and interframe.It is a composite algorithm with the connection of the recursive filtering algorithm and wavelet algorithm.Experiment proves that this method can effectively eliminate the X-ray imaging random noise.
