摘要
针对传统图像增强算法无法同时消除噪声和保持纹理的不足,从线性逆扩散的基本原理出发,提出了非线性逆扩散图像增强算法的原则,给出了适合的扩散系数。试验结果表明本算法有效地增强了图像,消除了图像中的噪声,能够保留图像中的细节纹理。
Traditional image enhancement algorithms could not eliminate noise and preserve textures at the same time. According to the principle of linear inverse diffusion, criteria on nonlinear inverse diffusion image enhancement algorithm were put forward and suitable diffusion coefficient was proposed, The experimental results show that this algorithm can enhance image effectively, eliminate the noise in the image and preserve the textures and details.
