| 摘 要： | 在非均匀介质表面，强光是漫反射光成分和镜面反射光成分的线性组合．结合非均匀介质表面反射特点和漫反射光成分之间的线性组合关系，文中提出一种新的基于测定光度的线性化方法，它可以计算出不同光照条件下图像之间的线性组合系数，并在此基础上提取非均匀介质表面漫反射光成分．实验结果表明，该方法可以有效地提取真实瓷器表面的漫反射光成分．

| Abstract: | On inhomogeneous media surface,highlights are linear combinations of diffusive and specular reflection components.Combining the reflection characteristics and linear relationship between diffusive reflection components on inhomogeneous media surface,in this paper,a new photometric linearization method is presented which estimates linear combination coefficients between realistic images under different lighting directions and extracts diffusive reflection components on inhomogeneous media surface.The experim... |
