A Step Towards Learning Contraction Kernels for Irregular Image Pyramid

Autor: Batavia, Darshan, González Díaz, María del Rocío, Kropatsch, Walter G.

A structure preserving irregular image pyramid can be computed by applying basic graph operations (contraction and removal of edges) on the 4 adjacent neighbourhood graph of an image. In this paper, we derive an objective function that classifies the

International audience; We investigate the intersection between hierarchical and superpixel image segmentation. Two strategies are considered: (i) the classical region merging, that creates a dense hierarchy with a higher number of levels, and (ii) t

International audience; Graph pyramids are often used to represent an image with various levels of details. Generalized pyramids have been recently defined in order to deal with images in any dimension. In this work, we show how to use generalized py
