摘　　要：提出了非线性逆扩散图像增强算法的原则,应用三次样条插值方法构造了该算法的扩散系数,得到了较好的图像增强效果。说明该算法能够对有微弱噪声的图像进行图像增强并保持细节纹理,其扩散系数既满足了逆扩散图像增强的原则,又容易构造。The criteria on nonlinear inverse diffusion image enhancement algorithm is put forward and suitable diffusion coefficient is proposed with cube-spine interpolation. Then the good image enhancement results are obtained. The experiments show that the algorithm can enhance images with low noise and preserve detailed textures. The diffusion coefficient complies with the criteria on inverse diffusion image enhancement and is easy to be interpolated.
