6.801 Machine Vision (Fall 2020, MIT OCW): Lecture 23 - Gaussian Image, Solids of Revolution, Direction Histograms, Regular Polyhedra

6.801 Machine Vision

6.801 Machine Vision (Fall 2020, MIT OCW). Instructor: Prof. Berthold Horn. This course is an introduction to the process of generating a symbolic description of the environment from an image. It covers the physics of image formation, image analysis, binary image processing, and filtering. Machine vision has applications in robotics and the intelligent interaction of machines with their environment. Students taking the graduate version complete additional assignments.

Lecture 23 - Gaussian Image, Solids of Revolution, Direction Histograms, Regular Polyhedra

Instructor: Prof. Berthold Horn. In this lecture, we cover more on the Gaussian images and extended Gaussian images (EGI), as well as integral Gaussian images, some properties of EGI, and applications of these frameworks.
