A fast progressive image transmission algorithm using linear bivariate splines

Abstract

Progressive image transmission provides a convenient User Interface when images are transmitted slowly. In this paper, we present a progressive image reconstruction scheme based on the multi-scale edge representation of images. In the multi-scale edge representation an image is decomposed into Most Significant Points which represent the strong edges and Insignificant Points which represent weak edges. Image re-construction is done based on the approximation of image regarded as a function, by a linear spline over adapted Delaunay triangulation. The proposed method progressively improves the quality of the reconstructed image till the desired quality is obtained. © 2010 Springer-Verlag Berlin Heidelberg.
