A Multiscale Image Representation Using Hierarchical (BV, L2 ) Decompositions
We propose a new multiscale image decomposition which offers a hierarchical, adaptive representation for the different features in general images. The starting point is a variational decomposition of an image, f = u0 + v0, where [u0, v0] is the minimizer of a J-functional, J(f, λ0;X,Y ) = infu+v=f { ‖u‖X + λ0‖v‖pY } . Such minimizers are standard tools for image manipulations (e.g., denoising, ...

متن کاملMultiscale Image Representation and Texture Extraction Using Hierarchical Variational Decomposition
In order to achieve a mutiscale representation and texture extraction for textured image, a hierarchical (BV, Gp, L ) decomposition model is proposed in this paper. We firstly introduce the proposed model which is obtained by replacing the fixed scale parameter of the original (BV, Gp, L 2 ) decomposition with a varying sequence. And then, the existence and convergence of the hierarchical decom...
متن کاملMultiscale image representation using scale-space theory
Image simplification reduces the information content of an image while preserving as much as possible its essential features, being frequently used as a preprocessing stage in several algorithms to suppress undesired details such as noise. In this paper, we explore the scale-space properties of a toggle operator defined using mathematical morphology operations. The scale-space theory is a multi...
متن کاملLocal scales and multiscale image decompositions
Article history: Received 17 April 2008 Revised 19 August 2008 Accepted 21 August 2008 Communicated by Charles K. Chui This paper is devoted to the study of local scales (oscillations) in images and use the knowledge of local scales for image decompositions. Denote by Kt(x)= ( e−2πt|ξ |2 )∨ (x), t > 0, the Gaussian (heat) kernel. Motivated from the Triebel–Lizorkin function space Ḟα p,∞ , we de...
