This article is concerned with the design and implementation of a system for real time monocular tracking of a moving object using the two degrees of freedom of a camera platform. Figure-ground segregation is based on motion without making any a priori assumptions about the object form. Using only the rst spatiotemporal image derivatives subtraction of the(More)
Invited Paper There is growing interest in performing aerial surveillance using video cameras. Compared to traditional framing cameras, videos provide the capability to observe ongoing activity within a scene and to automatically control the camera to track the activity. However, the high data rates and relatively small field of view of videos present new(More)
We address an active way of depth estimation using the mechanical degrees of freedom of a stereo vision system. A depth map will be computed in an action-perception cycle by using the control of gaze and vergence of the active system iterately. We apply a phase-based approach to compute disparity maps on diier-ent resolutions. Due to the phase-based(More)
We consider the problem of constructing a mathematical model for a specific type of marine cooling system. The system in question is used for cooling the main engine and auxiliary components, such as diesel generators, turbo chargers and main engine air coolers for certain classes of container ships. The purpose of the model is to describe the important(More)
PURPOSE Tissue phase velocity mapping (TPVM) is capable of reproducibly measuring regional myocardial velocities. However acquisition durations of navigator gated techniques are long and unpredictable while current breath-hold techniques have low temporal resolution. This study presents a spiral TPVM technique which acquires high resolution data within a(More)
