Image coding with iterated contourlet and wavelet transforms
This paper presents a new coding technique based on a mixed contourlet and wavelet transform. The redundancy of the transform is controlled by using the contourlet at fine scales ...

Adaptive Wavelet Packet Image Coding using an Estimation-Quantization Framework
In this paper, we extend the statistical model-based Estimation-Quantization (EQ) wavelet image coding algorithm introduced in [?] to include an adaptive transform component. For ...

A Wavelet Approach to Foveating Images
Motivated by applications of foveated images in visualization, we introduce the foveation transform of an image. We study the basic properties of these transforms using the multir...

Oriented wavelet transform on a quincunx pyramid for image compression
This paper presents a new image coding technique based on oriented 1D multiscale decompositions on a quincunx sampling grid. A transform obtained by adapting the lifting steps of ...
