; Bandera-Rubio, Antonio Jesús
; Sandoval-Hernández, Francisco
(Elsevier, 2003-10-13)
This paper presents a new segmentation technique for color images. It relies on building an irregular pyramid into a regular one, presenting only nodes associated to homogeneous color regions. Hence, the size of the irregular ... -
Case-based reasoning emulation of persons for wheelchair navigation.
Peula Palacios, José Manuel; Urdiales-García, Amalia Cristina; Herrero-Reder, Ignacio
; Fernández-Carmona, Manuel; Sandoval-Hernández, Francisco
(Elsevier, 2012)
Our approach is based on extracting meaningful data from real users driving a power wheelchair autonomously. This data is then used to train a case-based reasoning (CBR) system that captures the specifics of the driver via ... -
