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 a 1D wavelet transform along a local orientation is described. A quad-tree structure is used to efficiently code the orientation map, and optimized in the rate
