This paper presents a new approach to matching and segmenting multiple rigid motions using epipolar constraint. Epipolar geometry underlying the motion images are first recovered, and the epipolar equations are used to reduce search for correspondence from 2-dimensional to 1-dimensional, thus resolving the "aperture problem". Segmentation of images into different motions is simultaneous. Experimental results show that this approach is effective and efficient.

Object and motion recognition using the plane plus parallax displacement of conics

Parallax displacement is used to determine a relative 3D conic projective structure which can be used to segment groups of conics which have consistent motion and determines conic correspondence between three simultaneous views.

Unifying Stereo, Motion and Object Recognition via Epipolar Geometry

By recovering epipolar geometry underlying the images, the correspondence search problems in motion and object recognition can also be changed to be 1-dimensional, thus providing a framework to treat all these 3 problems in a unified way.

Rigid Body Segmentation and Shape Description from Dense Optical Flow Under Weak Perspective

An algorithm for identifying and tracking independently moving rigid objects from optical flow using the fact that each independently moving object has a unique epipolar constraint associated with its motion to distinguished motion discontinuities based on self-occlusion from those due to separate objects.

A new approach for the interpretation of optical flow fields is presented, where the flow field is partitioned into connected segments of flow vectors, where each segment is consistent with a rigid motion of a roughly planar surface.

Motion From Point Matches Using Affine Epipolar Geometry

This work defines the affine epipolar geometry for two such cameras, giving the fundamental matrix in this case and discussing its noise resistant computation, and presents a new framework that caters for errors and noise, and allows all available features to be used, without the need to select a frame explicitly.
