| 摘 要： | 给出了一种减小图像中的不均匀光照的方法。利用基于小波的非线性回归来估计降质图像的光照分布,再通过从原图中减去光照分布图达到减小不均匀光照的目的。对此方法和常用的双立方插值法的计算量进行了分析比较,证明此方法计算量小。最后取三幅图像进行了实验验证。

| Abstract: | A method to reduce non-uniform illumination in an image was presented. Wavelet-based regression estimation was used in this method to get an estimation of the illumination of degradation image. The complexity of this method was analyzed to show how can it works more rapidly than bi-cubic interpolation, which was widely used to reduce non-uniform illumination. Three images proceed with this method were shown, together with the result of bi-cubic interpolation. |
