Near lossless image compression using lossless Hartley like transform

Abstract

It is shown that the discrete Hartley transform (DHT) of length N = 4 can be used to perform an integer-to-integer transformation. This behavior of the DHT can be used to compute a 2-D separable lossless Hartley like transform (L-HLT). The performance of the L-HLT is found to be better than the DCT for near lossless image compression and wavelet-based filter bank approach for lossless compression.
