                         compression is shown, and the results of its application are 
                         accessed. Quincunx downsampling splits the spectrum of a image in 
                         two diamond-shaped subbands, and this allows the information to 
                         which the human eye is most sensitive to be preserved, and also 
                         requiring less bits in a lossy compression. In this paper, we show 
                         that quincunx subband coding actually delivers these results. 
                         Theory of lattices are briefly reviewed, and a technique that 
                         provides successive decompositions for a quincunx lattice is 
                         developed, which will allow multi-level decompositions. 
                         Simulations were carried out and the results are compared to the 
                         rectangular separable subband decomposition.",
