A multiresolution frequency domain method for estimating affine motion parameters
نویسندگان
چکیده
A novel approach to motion estimation is presented. The scheme employs a multiresolution model of 2-D motion, in which the motion within local regions at di erent scales is described in terms of a six parameter a ne model. A frequency domain method is used to estimate the local a ne motion parameters and a coarsene tracking algorithm is used to determine the global motion eld. Results of experiments performed on synthetic and natural image sequences illustrate the e ectiveness of the approach.

Enlarging Domain of Attraction for a Special Class of Continuous-time Quadratic Lyapunov Function Piecewise Affine Systems based on Discontinuous Piecewise
This paper presents a new approach to estimate and to enlarge the domain of attraction for a planar continuous-time piecewise affine system. Various continuous Lyapunov functions have been proposed to estimate and to enlarge the system’s domain of attraction. In the proposed method with a new vision and with the aids of a discontinuous piecewise quadratic Lyapunov function, the domain of attrac...
متن کاملImage Registration using Multiresolution Frequency Domain Correlation
This paper describes a correlation based image registration method which is able to register images related by a single global affine transformation or by a transformation field which is approximately piecewise affine. The method has two key elements: an affine estimator, which derives estimates of the six affine parameters relating two image regions by aligning their Fourier spectra prior to c...
متن کاملMultiresolution Motion Estimation Using an Affine Model
This report describes a novel method for estimating motion in image sequences. The approach is based on a multiresolution model in which the motion eld is considered to consist of a collage of di erent size regions with di erent local motions associated with them. The local motions are de ned in terms of an a ne model. The estimation procedure consists of a local component in which the a ne mot...

Motion-JPEG is a common video format for compression of motion images with highquality using JPEG standard for each frame of the video. During transmission through a noisychannel some blocks of data are lost or corrupted, and the quality of decompression frames decreased.In this paper, for reconstruction of these blocks, several temporal-domain, spatial-domain, andfrequency-domain error conceal...
متن کاملPseudoframe multiresolution structure on abelian locally compact groups
Let $G$ be a locally compact abelian group. The concept of a generalized multiresolution structure (GMS) in $L^2(G)$ is discussed which is a generalization of GMS in $L^2(mathbb{R})$. Basically a GMS in $L^2(G)$ consists of an increasing sequence of closed subspaces of $L^2(G)$ and a pseudoframe of translation type at each level. Also, the construction of affine frames for $L^2(G)$ bas...
