Morphological texture gradients: Definition and application to colour and texture watershed segmentation.
Jesús Angulo · Biblioteca Digital da Memória Científica do INPE (National Institute for Space Research) · 2007
This paper deals with a morphological approach to calculate texture gradients and it is shown how to use them for image segmentation according to the texture; and more generally, for joint colour/texture segmentation (i.e., structural segmentation). The starting point is a decomposition of the colour image into two components: the object layer and the texture layer. A multi-scale local analysis from the texture layer is built using morphological operators (openings/closings or levelings) to define the gradients of texture. The proposed texture gradient is then combined with the colour gradient to produce mixed segmentations by watershed.
