ABSTRACT: In this paper, we present a noise removal
technique by combining the P-M model with the LLT model. The combined technique
takes full use of the advantage of both filters which is able to preserve
edges and simultaneously overcomes the staircase effect. We use a weighting
function in our model, and compare this model with the P-M model as well as
other fourth-order functional both in theory and numerical experiment.
