Translation-invariant de-noising
, 1995
"... De-Noising with the traditional (orthogonal, maximally-decimated) wavelet transform sometimes exhibits visual artifacts; we attribute some of these – for example, Gibbs phenomena in the neighborhood of discontinuities – to the lack of translation invariance of the wavelet basis. One method to suppre ..."

On the translation invariance of wavelet subspaces
- J. Fourier Anal. Appl
"... Abstract. An examination of the translation invariance of V0 under dyadic rationals is presented, generating a new equivalence relation on the collection of wavelets. The equivalence classes under this relation are completely characterized in terms of the support of the Fourier transform of the wave ..."

Translation Invariant Propelinear Codes
- IEEE Trans. Information Theory
, 1997
"... A class of binary group codes is investigated. These codes are the propelinear codes, defined over the Hamming metric space F n , F = f0; 1g, with a group structure. Generally, they are neither abelian nor translation invariant codes but they have good algebraic and combinatorial properties. Line ..."

Translation invariants of Zernike moments
, 2002
"... Moment functions de ned using a polar coordinate representation of the image space, such as radial moments and Zernike moments, are used in several recognition tasks requiring rotation invariance. However, this coordinate representation does not easily yield translation invariant functions, which ar ..."

Translation Invariant Multiwavelet Transforms
, 1998
"... A translation invariant multiwavelet transform is introduced. It is shown that the associated correlation matrices satisfy a matrix-valued refinement equation implying a hidden basis wavelet representation. Properties of the correlation matrices such as regularity, approximation order, and vanishing ..."

Translation-Invariant Scene Grouping
"... Abstract—We present a new approach to the problem of grouping similar scene images. The proposed method characterizes both the global feature layout and the local oriented edge responses of an image, and provides a translation-invariant similarity measure to compare scene images. Our method is effec ..."

Supervised translation-invariant sparse coding
- IN: IEEE CONFERENCE ON COMPUTER VISION AND PATTERN RECOGNITION
, 2010
"... In this paper, we propose a novel supervised hierarchical sparse coding model based on local image descriptors for classification tasks. The supervised dictionary training is performed via back-projection, by minimizing the training error of classifying the image level features, which are extracted ..."
