A novel method for guidance of vision-based autonomous vehicles for indoor security
patrolling using scale-invariant feature transformation (SIFT) and vehicle localization …

This work presents a control strategy for mobile robots navigating in corridors, using the
fusion of the control signals from vision based controllers. To this aim two controllers are …

The environmental 3-D reconstruction is a strategic task in many contexts, above all, in
infrastructure inspection and vehicle/robot automatic motion. In this paper, we present a …

Smartphone applications based on object detection techniques have recently been
proposed to assist visually impaired persons with navigating indoor environments. In the …

The capability of identifying physical structures in an unknown environment is important for
autonomous mobile robot navigation and scene understanding. A methodology for detecting …

This paper proposes a new approach for determining the location of a mobile robot using
the image of a moving object. This scheme combines data from the observed position, using …

The pose estimation from visual sensors is widely practiced nowadays. The pose vector is
estimated by means of homographies and projection geometry. The integration of visual and …
