Image Restoration Based on
Neighborhood Information Optimization Method
Abstract：The image contained in the noise image information extraction is an important factor, but the existing degraded salt and pepper noise image recovery algorithm in denoising. This paper presents an improved optimization method based on neighborhood information filtering denoising algorithm, which is based on neighborhood information for the baseline and use of data analysis and optimization theory, the full realization of the suppression of image noise and retain the fine detail of the image. This paper first introduces the significance of the subject, and digital image processing concept, the common noise in the image denoising filters and MATLAB Overview; improved denoising filtering algorithm ideas and implementation steps are described, and and other filtering algorithm. The experimental results show that the filtering algorithm is simple and effective.
