We present a novel framework for multiple object tracking in which the problems of object detection and data association are expressed by a single objective function. The framework follows the Lagrange dual decomposition strategy, taking advantage of the often complementary nature of the two subproblems. Our coupling formulation avoids the problem of error propagation from which traditional “detection-tracking...
Voice conversion - the methodology of automatically converting one's utterances to sound as if spoken by another speaker - presents a threat for applications relying on speaker verification. We study vulnerability of text-independent speaker verification systems against voice conversion attacks using telephone speech. We implemented a voice conversion systems with two types of features and nonparallel...
We present a human motion model and animation for micro-sensor motion capture system. It consists of a sensor data-driven layered human motion model and an animation method using polygon group to achieve skin deformation. This method is based on biomechanics. The joints of human body were categorized according to the motion characteristics. Motion parameters estimated from sensor data are used to...
