Combining boundary and region features inside the combinatorial pyramid for topology-preserving perceptual image segmentation
Antúnez, Esther; Marfil-Robles, Rebeca; Bandera-Rubio, Antonio Jesús (Elsevier, 2012)
Combinatorial pyramids represent the image as a stack of successively reduced combi- natorial maps, which encode the whole image at different levels of abstraction. Within this framework, this paper proposes to conduct ... -
Hierarchical segmentation of range images inside the combinatorial pyramid
Marfil-Robles, Rebeca; Antúnez, Esther; Bandera-Rubio, Antonio Jesús (Elsevier, 2015)
RGB-D cameras are not only able to provide color (Red-Green-Blue -RGB-) informa- tion from the scene but also a relatively accurate cloud of 3D points. Using information coming from this organized cloud, it is possible ... -
