4 Captions Table 1. Angular displacements of a camera which is rotated of a xed amount around an axis orthogonal to the image plane between consecutive frames: the rst row reports angular displacements as measured with a goniome-ter, whilst the second row refers to computed values from vanishing points. Fig. 1. Extraction of vanishing points. a) A corridor at IRST; b) edges approximated by stra...

We propose a novel approach for face tracking, resulting in a visual feedback loop: instead of trying to adapt a more or less realistic arti"cial face model to an individual, we construct from precise range data a speci"c texture and wireframe face model, whose realism allows the analysis and synthesis modules to visually cooperate in the image plane, by directly using 2D patterns synthesized b...

This study demonstrated that a simple mechanical model of global tongue movement in parallel sagittal planes could be used to quantify tongue motion during speech. The goal was to represent simply the differences in 2D tongue surface shapes and positions during speech movements and in subphonemic speech events such as coarticulation and left-to-right asymmetries. The study used tagged Magnetic ...

This paper describes a novel video mosaicing method based on extrinsic camera parameter estimation. With our method, a mosaic image without perspective distortion can be generated, even if none of the input image plane is parallel to the target document. Thus, users no longer have to take special care in holding the camera so that the image plane in the reference frame is parallel to the target...

In this paper, we have presented a novel tracking method aiming at detecting objects and maintaining their label/identification over the time. The main key factors of this method are to use depth information and different strategies to track objects under various occlusion scenarios. The foreground objects are detected and refined by background subtraction and shadow cancellation. The occlusion...

Detailed analyses of reading and nonlexical tasks by three patients with unilateral spatial neglect (USN) secondary to stroke indicate that the USN in each of these patients affects the left side (contralateral to brain damage) of the viewer, with respect to the viewer's head, mid-sagittal plane of the body, or line of sight. In one case, the neglect was further specified as concerning the left...

Object tracking is a process that follows a specific object through some consecutive frames of images to determine the movement of that object relative to the other objects of those frames. Simply, tracking is the problem of estimating the trajectory of an object in the image plane as it moves around a scene. Depending on the tracking domain, a tracker can also provide partial and full object o...
