The Poisson Equation in Image & Shape Processing
(600.657)


This seminar will survey a variety of applications of the Poisson in the domain of computer graphics. The course will begin by reviewing the Poisson equation and several numerical methods for solving the associated linear system. Next, we will consider applications of the Poisson equation to challenges in image editing, including HDR compression, inpainting, and texture synthesis. Finally, we will consider generalizations of the system to 3D shapes, including applications such as mesh deformation and surface reconstruction.
General Breakdown
This course will be broken up into two general areas. We will begin by considering applications of the Laplacian to problems in image processing and then we will consider applications to mesh editing.

Student Responsibilities
Students will be regularly assigned papers to read, and two students each week will present papers to the seminar. Additionally, there will be a final project that students will be expected to submit by the end of the semester (to be done in groups of two). Students will submit a written proposal for the project by the middle of the semester (October 17th) and will present the results of their projects to the class in the last two lectures (December 5th and 10th).
