Contractivity of fractal transforms for image coding
Indexing terms: Coding, Image processing, Fractal transforms In this letter the contractivity of existing fractal transforms for use in image compression schemes is examined. The coding process is described as nonlinear transformation in the finite dimensional euclidean vector space. We derive sufficient conditions for contractivity based on the spectral norm and the spectral radius of the tran...
متن کاملOrthogonal pyramid transforms for image coding
We describe a set of pyramid transforms that decompose an image into a set of basis functions that are (a) spatial-frequency tuned, (b) orientation tuned, (c) spatially localized, and (d) self-similar. For computational reasons the set is also (e) orthogonal and lends itself to (f) rapid computation. The systems are derived from concepts in matrix algebra, but are closely connected to decomposi...
متن کاملCombining wavelet and fractal coding for 3-D video coding
Smooth regions and edges are very self similar and can be coded efficiently by fractal coders. One problem of fractal image coding is to achieve a high quality or a lossless representation of an image. This can be overcome by a hybrid coding approach as proposed by the authors in [3]. An extension to 3-D fractal video coding is described in [4]. Due to the block based algorithm, however, blocki...
متن کاملGeneralized Linear-Phase Lapped Orthogonal Transforms
The general factorization of a linear-phase paraunitary filter bank (LPPUFB) is revisited and we introduce a class of lapped orthogonal transforms with extended overlap (GenLOT). In this formulation, the discrete cosine transform (DCT) is the order-l GenLOT, the lapped orthogonal transform is the order-:! GenLOT, and so on, for any filter length which is an integer multiple of the block size. A...
متن کاملWavelet-Based Fractal Transforms for Image Coding with No Search
The compression performance of fractal image coding is considered using the wavelet-based fractal coder with no search or classi cation of the domain blocks. A new partitioning scheme is introduced as a variant of earlier schemes which further improves the compression performance. The Wavelet-Based Fractal Transform (WBFT) links the theory of multiresolution analysis (MRA) with iterated functio...
