Interesting results of color clustering for the iris images in the UBIRISv1 database are presented. The iris colors are characterized by feature vectors with 80 components corresponding to histogram bins computed in the CIELAB color space. The feature extraction is applied to the first session eye images after undergoing an iris segmentation process. An agglomerative hierarchical algorithm is used...
Cognitive aspects implemented in computational processes establish frames to model human actions relative to the human corresponding senses. Vision is one of them. To conceive appropriated artificial architectures, behavior manifestations and brain structural proprieties are intensively studied. Physiology is modeled in simplified schemas in order to be implemented in virtual systems and machine models...
