Abstract:

Specific to the reflected light problem on the surface of transparent body, the polarization characteristics of the reflection region are analyzed, and a polarization characterization model combining the reflection and transmission effects is established. On the basis of the polarization characteristic analysis, the minimum value of normalized cross-correlation (NCC) coefficient between transmission and reflection images is solved through the gradient descent method, and their polarization degrees under the minimum correlation are acquired. According to the distribution relations of the transmitted and reflected lights in perpendicular and parallel directions, reflection separation is realized via the polarized orthogonality difference algorithm based on the degree of reflection polarization and the degree of transmission polarization.

Key words: reflection separation, transparent object, correlation, polarization characteristics
