FROM LOCAL POLYNOMIAL APPROXIMATION TO POINTWISE SHAPE-ADAPTIVE TRANSFORMS: AN EVOLUTIONARY NONPARAMETRIC REGRESSION PERSPECTIVE
Alessandro Foi, Vladimir Y. Katkovnik · 2011
In this paper we review and discuss some of the theoretical and practical aspects, the problems, and the considerations that pushed our research from the one-dimensional LPA-ICI (local polynomial approximation- interesection of conÞdence intervals) algorithm [27] to the development of powerful transform-based methods for anisotropic image
