چکیده

In this paper, we propose a novel method for synthesizing super-resolved images from image sequence taken with uncalibrated moving camera by integrating all frames in the sequence based on projective geometry between the frames. In this method, assuming that the object scene can be approximated with multiple plane patches, all frames in the input image sequence are registered with the fundamental matrices between the frames, and then integrated by transforming with homographic matrices. For reducing the registration error, the blur mount in the integrated image is estimated so that the sub-pixel order registration between the frames can be achieved. For demonstrating the effectiveness of the proposed method, we confirm that the proposed method improves the resolution of the synthesized image comparing with the input image sequence.

Linear and Bilinear Subspace Methods for Structure from Motion

Structure from Motion (SFM), which is recovering camera motion and scene structure from image sequences, has various applications, such as scene modeling, robot navigation and object recognition. Most of previous research on SFM requires simplifying assumptions on the camera or the scene. Common assumptions are a) the camera intrinsic parameters, such as focal lengths, are known or unchanged th...

Jacobian images of super-resolved texture maps for model-based motion estimation and tracking

We present a Kalman filter based approach to perform model-based motion estimation and tracking. Unlike previous approaches, the tracking process is not formulated as an SSD minimization problem, but is developed by using texture mapping as the measurement model in an extended Kalman filter. During tracking, a super-resolved estimate of the texture present on the object or in the scene is obtai...

A ne Structure from Line Correspondences with Uncalibrated A ne Cameras Long QUAN and Takeo KANADE

|This paper presents a linear algorithm for recovering 3D a ne shape and motion from line correspondences with uncalibrated a ne cameras. The algorithm requires a minimum of seven line correspondences over three views. The key idea is the introduction of a one-dimensional projective camera. This converts 3D a ne reconstruction of \line directions" into 2D projective reconstruction of \points". ...

Visual servoing of robots with uncalibrated robot and camera parameters

This paper presents a new controller to regulate a set of feature points on the image plane to desired positions by controlling motion of a robot manipulator in uncalibrated environments. This controller is designed to cope with both the unknown camera parameters and the unknown robot parameters. The controller employs the depth-independent image Jacobian matrix to map the image errors onto the...

Submitted to Image and Vision Computing Uncalibrated Euclidean Reconstruction: A Review

This paper provides a review on techniques for computing a three-dimensional model of a scene from a single moving camera, with unconstrained motion and unknown parameters. In the classical approach, called autocalibration or self-calibration, camera motion and parameters are recovered rst, using rigidity; then structure is easily computed. Recently, new methods based on the idea of stratiicati...
