Balanced Multiwavelets and Application in Image Compression
نویسندگان
چکیده
Multiwavelet is attracting more and more attention for its good properties such as orthogonality, symmetry, compactly supported, high vanishing moment and balance contrast with the traditional wavelet. These properties, along with optimum time-frequency resolution (OPTFR) are all very important in image processing. Multifilter banks having all properties of symmetry, balancing, optimum time-frequency resolution, arbitrary order vanishing moment, orthogonality and compactly supported together are constructed for the first time. Application experiments in image compression showed that, most of our multifilter banks outperform the best tools known as multiwavelet SA4 or approximate wavelet DB4 in compression with texture image.

Stereo correspondence matching: Balanced multiwavelets versus unbalanced multiwavelets
This paper investigates the efficiency of unbalanced versus balanced multiwavelets in stereo correspondence matching. A multiwavelet transform is first applied to a pair of stereo images to decorrelate them into a number of subbands. Information in the approximation subbands of an unbalanced multiwavelet carries different spectral content of the input image while the balanced multiwavelet appro...
متن کاملWavelet transforms for vector fields using omnidirectionally balanced multiwavelets
Vector wavelet transforms for vector-valued fields can be implemented directly from multiwavelets; however, existing multiwavelets offer surprisingly poor performance for transforms in vector-valued signalprocessing applications. In this paper, the reason for this performance failure is identified, and a remedy is proposed. A multiwavelet design criterion, omnidirectional balancing, is introduc...
متن کاملBalanced Multiwavelets Theory and Design - Signal Processing, IEEE Transactions on
This correspondence deals with multiwavelets, which are a recent generalization of wavelets in the context of time-varying filter banks and with their applications to signal processing and especially compression. By their inherent structure, multiwavelets are fit for processing multichannel signals. This is the main issue in which we will be interested here. The outline of the correspondence is...
متن کاملConstruction of Nonseparable Multiwavelets for Nonlinear Image Compression
A procedure for the construction of balanced orthogonal nonseparable quincunx multiwavelets, having filters with good lowpass properties, is introduced. Thematrix filter bank is viewed as the polyphasematrix of other filters, uponwhich the lowpass condition is imposed. The multiscaling functions obtained are plotted by means of the cascade algorithm. The process of transforming an image with th...
