Research on Filtering and Noise for Aerial Image
摘要
Abstract
The aerial image with noise is introduced. Aiming at the characteristics of aerial image has both white Gauss noise and pulse noise, a denoising method based on four-order PDE and improved adaptive median filter is proposed for data processing. An improved median filter was used to remove the pulse noise, and the anisotropy and the boundary retention characteristics with four-order PDE were used for filtering image. The experiment indicates that this method can filter noise and hold boundary, avoid staircase effect, and has strong robustness.关键词
