چکیده
Based on our previous work on the use of subspace distances for the outlier deiection problem in video sequences under afFne projection. this paper reports ourfurther analysis of the problem and presents fwo algorithms for computing the reprojection errors of imagefeatures in the outlier detection process. Extensive experiments on real video sequences have been conducted to verrfi the performance ofthe algorithms. The key contributions ofthe paper are presentation offhe relationship befween subspace distances and reprojection errors and demonstration thar repmjection errors can be estimated without erplicitly computing the projective structure.

Passivity-Based Stability Analysis and Robust Practical Stabilization of Nonlinear Affine Systems with Non-vanishing Perturbations
This paper presents some analyses about the robust practical stability of a class of nonlinear affine systems in the presence of non-vanishing perturbations based on the passivity concept. The given analyses confirm the robust passivity property of the perturbed nonlinear systems in a certain region. Moreover, robust control laws are designed to guarantee the practical stability of the perturbe...
متن کاملUncalibrated Factorization Using a Variable Symmetric Affine Camera
In order to reconstruct 3-D Euclidean shape by the TomasiKanade factorization, one needs to specify an affine camera model such as orthographic, weak perspective, and paraperspective. We present a new method that does not require any such specific models. We show that a minimal requirement for an affine camera to mimic perspective projection leads to a unique camera model, called symmetric affi...
متن کاملStructure and Motion Estimation
This tutorial is concerned with the structure and motion estimation from the sequence of images taken with an uncalibrated affine camera. This problem was first addressed by Koenderink and van Doorn [1]. We will address the following problems: • Calibrated and uncalibrated affine camera models; • Tomasi and Kanade factorization method; • Sequential estimation of the structure and motion paramet...
متن کاملA Factorization Approach to Inertial Affine Structure from Motion
We consider the problem of reconstructing a 3-D scene from a moving camera with high frame rate using the affine projection model. This problem is traditionally known as Affine Structure from Motion (Affine SfM), and can be solved using an elegant low-rank factorization formulation. In this paper, we assume that an accelerometer and gyro are rigidly mounted with the camera, so that synchronized...
متن کاملA Modified Digital Image Watermarking Scheme Based on Nonnegative Matrix Factorization
This paper presents a modified digital image watermarking method based on nonnegative matrix factorization. Firstly, host image is factorized to the product of three nonnegative matrices. Then, the centric matrix is transferred to discrete cosine transform domain. Watermark is embedded in low frequency band of this matrix and next, the reverse of the transform is computed. Finally, watermarked ...
