Infinitesimal Motion Estimation from Multiple Central Panoramic Views∗
نویسندگان
چکیده
We present an algorithm for infinitesimal motion estimation from multiple central panoramic views. We first derive the optical flow equations for central panoramic cameras as a function of both pixel coordinates and back-projection rays. We then derive a rank constraint on the optical flows across many frames, which must lie in a six dimensional subspace of a higher-dimensional space. We then propose factorization approach for recovering camera motion and scene structure. We present experimental results on a real image sequence.

Multibody motion estimation and segmentation from multiple central panoramic views
We present an algorithm for infinitesimal motion estimation and segmentation from multiple central panoramic views. We first show that the central panoramic optical flows corresponding to independent motions lie in orthogonal ten-dimensional subspaces of a higher-dimensional linear space. We then propose a factorization-based technique that estimates the number of independent motions, the segme...
متن کاملDirect Methods for Visual Scene Reconstruction
There has been a lot of activity recently surrounding the reconstruction of photorealistic 3-D scenes and high-resolution images from video sequences. In this paper, we present some of our recent work in this area, which is based on the registration of multiple images (views) in a projective framework. Unlike most other techniques, we do not rely on special features to form a projective basis. ...
متن کاملShape recovery from multiple views: a parallax based approach
Given two arbitrary views of a scene under central projection, if the motion of points on a parametric surface is compensated, the residual parallax displacement eld on the reference image is an epipolar eld. The parallax magnitude at a point, after suitable scaling, is an a ne invariant; if the surface aligned is a plane, it is directly proportional to the height of the point from the plane an...
متن کاملSpherical Panoramas for Pan-Tilt Camera Motion Compensation in Space-Variant Images
In active vision scenarios, the motion of the observer induces an apparent motion in the image plane. One approach for camera motion compensation is the use of panoramic images, representing the scene at the different positions of the camera. In this work, an approach to build spherical panoramic views from a pan-tilt camera is described, which is based on background updating techniques. Intere...
متن کاملSimultaneous Tracking of Head Poses in a Panoramic View
In this paper we present an approach to simultaneously estimate gaze directions of multiple people in the view of a panoramic camera. Human faces are located and tracked using a probabilistic skin-color model and motion detection. Neural networks are used to estimate head poses of the detected faces. With this approach, it is possible to simultaneously track the locations of multiple people aro...
