Since specular reflection often exists in the real captured images and causes
deviation between the recorded color and intrinsic color, specular reflection
separation can bring advantages to multiple applications that require
consistent object surface appearance. However, due to the color of an object is
significantly influenced by the color of the illuminat
使用方向线性偏振旋转作为区分直接反射和镜面间接反射的特征，本论文提出了一种应对金属物体镜面间接反射的新型分解方法，通过主动旋转入射光的线性偏振并分析反射光的旋转方向，对反射率组分进行分解，实验证明了该方法在分解金属物体镜面间接反射方面的有效性，并展示了该方法与其他分解方法相结合进行光输运详细分析的能力，对强镜面间接反射下的 3D 测量精度提升方面也取得了良好效果。
