This work presents a strategy to track and describe the boundary of an environmental surface using a sequence of incomplete boundary images coming from an UAV with a camera onboard. The algorithm uses all captured images to feed the trajectory, which drives the UAV towards the next point to take the next shot, until the identification is completed. The multiple patterns of the input image make the...
We present a novel unsupervised inter-camera trajectory correspondence algorithm that does not require prior knowledge of the camera placement. The approach consists of three steps, namely association, fusion and linkage. For association, local trajectory pairs corresponding to the same physical object are estimated using multiple spatio-temporal features on a common ground-plane. To disambiguate...
This paper describes a technique for recovering 3-D shape of a non rigid object employing a single camera. 3-D modeling of a non-rigid object has been studied employing multiple cameras. However it can be realized even by a single camera on condition that the object concerned is composed of a set of rigid objects. Experimental results show effectiveness of the proposed technique.
