Rolon Garrido, Julio Cesar; Ortega, Antonio; Salembier Clairon, Philippe Jean (2009)
Open AccessThis paper introduces the design of context-based models of contours in the wavelet domain, which are used to construct generalized lifting (GL) mappings for image compression. The GL context-based mapping may significantly ...
Performance evaluation of probability density estimators for unsupervised information theoretical region merging Calderero Patino, Felipe; Marqués Acosta, Fernando; Ortega, Antonio (2009)
Open AccessInformation theoretical region merging techniques have been shown to provide a state-of-the-art unified solution for natural and texture image segmentation. Here, we study how the segmentation results can be further ...
