Abstract

MENDIOLA-SANTIBANEZ, Jorge D  and  TEROL-VILLALOBOS, Iván R. Quantifying Contrast Methods through Morphological Gradient. Comp. y Sist. [online]. 2005, vol.8, n.4, pp.317-333. ISSN 1405-5546.

In this work two quantifying contrast models are proposed. The first contrast measure method employs the concept denominated difference of contrast; while the second one takes in consideration the luminance gradient concept. These models allow the selection of the best parameters in a group of output images obtained from the application of the morphological toggle mappings with size criteria. These morphological transformations have the characteristic of modifying the output contrast based on some proximity criterion. In order to illustrate the performance of these quantifying contrast models, a number of images were processed and compared at pixel and partition level.

Keywords : Contrast Measure; Toggle Mappings; Flat Zone; Partition; Visualization.
