Curvature-based functional for color image restoration

Ponente(s): Keny Geovany Chin Parra

The Polyakov action is a functional (adopted from high energy physics) used in variational models for color image restoration. I will provide a generalization of the functional proposed by Sochen, Kimmel, and Malladi in 1998, based on the Polyakov action. To achieve this, I will construct an abstract algebra defined on each pixel of the image and later integrate the principal curvatures of the image into the proposed model.
