Comparative performance of pyramid data structures for progressive image transmission

A review of various pyramid data structures for progressive image transmission, focusing on the steps involved in forming the pyramid and the performance comparisons, is presented. The simple mean pyramid, its variants including the truncated mean, reduced-sum, difference, reduced-difference and S-transform pyramids, and the more general Laplacian pyramid are discussed. It is also shown that the use of an interpolation function improves the quality of the full-resolution approximations both objectively and subjectively.<
