# Structure from Motion Without Correspondence: General Principle

## Abstract

A general principle is given for detection of the 3D structure and motion from an image sequence without using point-to-point correspondence. The procedure consis ts of two stages: (i) determination of the "fl ow parameters" from "features" without using correspondence an d (ii) computation of the 3D structure and motion from these flow parameters. The first stage is d one by solving equations of functionals, and the secon d stage is described in analytical expressions.
