Adaptive Switching Interpolation Algorithm for Filtering Salt and Pepper Noises in Image
Jin Wei-dong · Journal of Southwest Jiaotong University · 2009
An adaptive switching interpolation filter was proposed using Newton interpolation method to remove salt and pepper noises in an image.Maximum-minimum noise detector and adaptive window size method were combined to identify pixels which are likely to be corrupted by noises.Then the image is restored by iterative interpolation to replace each noised pixel with a non-noised or repaired pixel in its vicinity.Simulation results on images with noise densities from 10% to 90% show that the proposed filter performs well in reducing salt and pepper noise in images with good detail-preservation.
