Abstract
The median adaptive predictor (MAP) is widely used in many modem-day lossle ss picture compression algorithms, including the new JPEG-LS international standard. The basis of MAP is the crisp median operator. In this article we describe how we may fuzzify the MAP and obtain two new "soft" predictors, We compare the performance of the new predictors with the crisp MAP by comp ressing several test pictures and show the new predictors always perform be tter than the crisp MAP.
