一种噪声密度检测自适应选择策略的滤波算法
Adaptive-selection filtering strategy algorithm on noise density detection
摘要
Abstract
This paper proposed an adaptive-selection filtering strategy algorithm on noise density detection for the filter problem that gray-scale was polluted by salt and pepper noise of different degree. Firstly, it detected the noise density of the polluted image,according to the detection results,the image was judged as either light polluted image or severe polluted image. For the former, it took 3×3 windows switching median filter algorithm based on statistical threshold. For the latter, it took first 3×3 last 5×5 windows switching median filter algorithm based on statistical threshold. Experimental results indicate that the proposed algorithm not only has strong adaptability but also has better image detail preservation and strong denoising ability.关键词
