This paper focus on one of the major problems in modelbased object tracking, the problem of how to dynamically update the model to adapt changes in the structure and appearance of the target object. We adopt Irregular Graph Pyramids to hierarchically represent the topological structure of a rigid moving object with multiresolution, making it possible to add new details observed from an approach...

Dominant features of spatial data are connected structures or patterns that emerge from location-based variation and manifest at specific scales resolutions. To identify dominant features, we propose a sequential application multiresolution decomposition variogram function estimation. Multiresolution separates into additive components, in this way enables the recognition their features. A dedic...

In this paper, we extend our original work on multiresolution learning, and present a new concept and method of adaptive neural activation functions in multiresolution learning, to maximize the learning efficacy of multiresolution learning paradigm for neural networks. Real-world sunspot series (yearly sunspot data from 1700 to 1999) prediction has been used to evaluate our method. We demonstra...

An edge coding scheme based on chain code representation in a multiresolution image coding context is presented. Our method enhances the coding schemes that describe the source structure with Markov models, by using also an a priori knowledge from the previous decoded resolution images. Experiments using adaptive arithmetic coding have shown up to a 5% improvement for the bitrate compared to a ...

The downsampling of a discrete wavelet transform (DWT) has a side effect of the lack of shiftinvariance. There are two main solutions for this effect: one is the stationary wavelet transform (SWT), which does not apply downsampling. The other is the complex DWT (CDWT), which uses dual multiresolution analysis (MRA). We choose the CDWT as a target of research. It is well known that wavelet funct...

Many realistic protein-engineering design problems extend beyond the computational limits of what is considered practical when applying all-atom molecular-dynamics simulation methods. Lattice models provide computationally robust alternatives, yet most are regarded as too simplistic to accurately capture the details of complex designs. We revisit a coarse-grained lattice simulation model and de...

Motivated by the multivariate wavelet theory, and by the spectral theory of transfer operators, we construct an abstract affine structure and a multiresolution associated to a matrix-valued weight. We describe the one-to-one correspondence between the commutant of this structure and the fixed points of the transfer operator. We show how the covariant representation can be realized on Rn if the ...

A multiresolution source code is a single code giving an embedded source description that can be read at a variety of rates and thereby yields reproductions at a variety of resolutions. The resolution of a source reproduction here refers to the accuracy with which it approximates the original source. Thus, a reproduction with low distortion is a “high-resolution” reproduction while a reproducti...
