It is important to enable a robot to manipulate a target object that has no 3-D model information and is situated in an environment with other unknown objects nearby. This poses an open problem of how to combine perception and manipulation to enable the robot to build an appearance-based model of the target object on the spot to facilitate further manipulation of the object while avoiding the other...
Global object redundancy (GOR), as opposed to local spatial/temporal redundancies in a single video clip, is a new form of redundancy common in multisource surveillance video data (MSVD). GOR is induced by the repetition of foreground objects across multiple cameras, and becomes influential as the number of objects increases. Eliminating GOR considerably improves MSVD coding efficiency. In an effort...
In this paper, we exploit a new type of data redundancy in the multisource surveillance video to reduce the huge gap between the growth rate of the data and the video compression rate. Global redundancy caused by correlated appearances of moving objects in multiple videos consists of model similarity, spatial correlation and temporal consistency. Therefore, we propose a global coding scheme of moving...
Corner detection is a fundamental step in visual measurement, and it is also an important factor which affects the real-time performance in measurement. In order to improve the real-time performance of corner detection, a fast detection method of checkerboard corners based on the combination of template matching and Harris Operator is proposed. First, template matching model is founded based on the...
We present a catadioptric projector analogous to a catadioptric camera by combining a commodity digital projector with additional optical units. We show that, by using specially shaped reflectors/refractors, catadioptric projectors can offer an unprecedented level of flexibility in aspect ratio, size, and field of view. We also present efficient algorithms to reduce projection artifacts in catadioptric...
