1 June 1991 Novel nonlinear filter for image enhancement
Author Affiliations +
Recently, a very simple nonlinear algorithm, the so-called Teager's algorithm, has been introduced to calculate the energy of a 1D sequence. In this paper, this algorithm is extended to 2D signals and applied to the constant enhancement of images. Initial simulation results indicate that the proposed approach yield a superior and visually pleasing enhancement of natural images. The new algorithm is very simple and permits fast implementation.
