Research on Adaptive Weighted Median Filter in Seismic Image
Lei He · Journal of Chongqing University of Science and Technology · 2010
Earthquake image is mainly random noise,with a median filter can effectively restrain random noise,this paper presents a new adaptive weighted median filter algorithm.According to the pollution situation right domain,this method analyzes seismic image noise distribution characteristic.This algorithm is proved in improving the performance of the median filtering effectively,eliminating the earthquake image noise,keeping good image edge details,and improving the signal-to-noise ratio of seismic image.
