Geometry in computer vision

Structure from motion

Structure from motion (SfM) is a photogrammetric range imaging technique for estimating three-dimensional structures from two-dimensional image sequences that may be coupled with local motion signals. It is studied in the fields of computer vision and visual perception. In biological vision, SfM refers to the phenomenon by which humans (and other living creatures) can recover 3D structure from the projected 2D (retinal) motion field of a moving object or scene. (Wikipedia).

Introduction to compression

In a structure, tension and compression are fundamentally different due to bucking instabilities. This video is a qualitative introduction to buckling and material in compression. Video lectures created for Mechanics of Solids and Structures course at Olin College

Introduction to Tension

So far we have computed loads in structures. Now we consider how the material deforms in response to these forces. This lecture introduces what happens to a simple bar in tension. These videos were created for Mechanics of Solids and Structures at Olin College.
