There are two main challenges, drift and scale ambiguity, restricting monocular visual odometry from an extensive application on real autonomous navigation. In this paper, an iterative localization framework is presented to globally localize a mobile vehicle equipped with a single camera and a freely available digital map. Inspired by the concept of cloud, a new Gaussian–Gaussian Cloud model is proposed...
Computer lip-reading systems are usually designed to work using a full-frontal view of the face. However, many human experts tend to prefer to lip-read using an angled view. In this paper we consider issues related to the best viewing angle for an automated lip-reading system. In particular, we seek answers to the following questions: 1) Do computers lip-read better using a frontal or a non-frontal...
This paper presents a gesture recognition framework using voxel data obtained through visual hull reconstruction from multiple cameras. View-invariant pose descriptors are extracted by projecting voxel data onto a low dimensional pose coefficient space using multilinear analysis. Gestures are then treated as sequences of pose descriptors and represented by hidden Markov models for gesture recognition...
