Image and Video Special Effects based on Geometry and Partial
Location: IRMACS Theatre
Presenter: Professor Guillermo Sapiro, Electrical & Computer Engineering, University of Minnesota
Abstract: In this talk I will show how fundamental problems in image and
video editing can be efficiently addressed with fundamental mathematics.
After a brief introduction to the area of image inpainting, meaning the
modification of an image in a non-detectable form, I will concentrate on
image and video colorization, the art of colorizing black and white data.
I will show the connection of this problem with Hamilton-Jacobi equations
and distance functions, and a technique to compute them in linear time. I
will also describe how to use similar techniques for other special
effects and user-oriented image segmentation.
The talk will have a combination of fundamental math, computational
tools, and a lot of examples.
