Title:

    Simultaneous estimation of reflectance parameters from images

Presenter(s)/Author(s):



Abstract:


     Although the reflection model has been improved to generate realistic images, it is difficult to determine appropriate values of specular and diffuse reflectance parameters. Sato et al. [Sato et al. 1997]  proposed an approach to estimate each parameter from images of  actual objects by separating the observed data into two reflection  components. However, it is not necessarily possible to distinguish  the mixed data into two reflections precisely. This paper presents  a method to estimate both reflectance parameters simultaneously from real images without separating the specular and diffuse components. We have defined an integrated space as two reflection characteristics and developed a procedure to determine the model parameters from distribution of the observed data in the space.
