<title>Enlargement of digital images by using multi-neural networks</title>

Abstract

We have presented the enlargement neural network (NN) [3] for edge-preserving image interpolation, which is based on the non-linear procedure which is presented by Greenspan [2] . In this paper, we present a novel enlargement multi-neural network (MNN) which is an extended the enlargement NN. Simulation results show the superior performances of the proposed new approach with respect to other interpolation techniques as the enlargement NN and the Greenspan's method.
