LHE (logarithmical hopping encoding) is a computationally efficient image compression algorithm that exploits the Weber-Fechner law to encode the error between colour component predictions and the actual value of such components. More concretely, for each pixel, luminance and chrominance predictions are calculated as a function of the surrounding pixels and then the error between the predictions and the actual values are logarithmically quantised. The main advantage of LHE is that although itdoi:10.1049/iet-ipr.2014.0421 fatcat:ra7boscjljd4nkqlhc3qg3ljdm
