Paper Abstract

We propose a novel specularity removal method based on reflection component separation and joint bilateral filtering. In general, specularities in images are represented as the linear combination of diffuse and specular reflection components in homogeneous objects. Although diffuse and specular components are correctly classified by reflection component separation, some illumination effects still remain in diffuse images due to the inaccurate illumination chromaticity estimation. Therefore, we refine the separated diffuse components using a joint bilateral filter. We test our method on both synthetic and real images, and the experimental results demonstrate that the proposed method outperforms the state-of-the-art ones in specularity removal.
