Discrete bandelets with geometric orthogonal filters
This paper describes the construction of second generation bandelet orthogonal bases. The decomposition on a bandelet basis is computed using a wavelet filter bank followed by ada...

VQ-adaptive block transform coding of images
—Two new design techniques for adaptive orthogonal block transforms based on vector quantization (VQ) codebooks are presented. Both techniques start from reference vectors that a...

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 ...

Lapped-orthogonal-transform-based adaptive image watermarking
A robust, invisible watermarking scheme is proposed for digital images, where the watermark is embedded using the blockbased lapped orthogonal transform (LOT). The embedding proces...

Weighted Adaptive Lifting-Based Wavelet Transform for Image Coding
In this paper, a new weighted adaptive lifting (WAL)-based wavelet transform is presented. The proposed WAL approach is designed to solve the problems existing in the previous adap...
