A robust image representation method against illumination and occlusion variations

作者：

Highlights：

• A novel GSR model that explores inherent geometric structure of the image.

• An analysis shows that the GSR model is a generalized solution to illumination reflectance model.

• An analysis shows that the proposed method can alleviate the effects of occlusion effectively.

• Extensive experiments prove the proposed method is robust to occlusion and illumination changes.
