Video-based eye tracking is a valuable technique in various research fields. Numerous open-source eye tracking algorithms have been developed in recent years, primarily designed for general application with many different camera types. These algorithms do not, however, capitalize on the high frame rate of eye tracking cameras often employed in psychophysical studies. We present a pupil detectio...

The underwater hydraulic manipulator's challenging working condition, such as the unknown payload, varying speed, and hydraulic actuator’s dynamics, makes common controller invalid. In this paper, based on the nonlinear control theory, the adaptive robust control method is proposed to enhance the joint tracking accuracy, the controller can also compensate the interactive dynamic effects between...

In dealing with a dynamic world, people have the ability to maintain selective attention on a subset of moving objects in the environment. Performance in such multiple-object tracking is limited by three primary factors-the number of objects that one can track, the speed at which one can track them, and how close together they can be. We argue that this last limit, of object spacing, is the roo...

In this paper, we propose a novel on-line visual tracking framework based on Siamese matching network and metalearner network which runs at real-time speed. Conventional deep convolutional feature based discriminative visual tracking algorithms require continuous re-training of classifiers or correlation filters for solving complex optimization tasks to adapt to the new appearance of a target o...

In this paper, we present a new technology to track multiple active Tangible User Interfaces (TUI) on a projection table. We use a commercial high speed infrared tracking camera with modified firmware. With a special tracking method, we reach update rates of up to 250 Hz with low latencies. At this tracking rate, we are able to track the position, state and the orientation of more than 10 activ...

Compared with the traditional tracking problem, underwater 3-D passive manoeuvring target faces following challenging problems: (1) Since signal propagation delay is varying and unknown, relationship between two adjacent states hard to describe; (2) limited by environment, it more difficult establish a motion model; (3) speed of acoustic varies depth, path will be curved instead straight. Vario...

Recently, Siamese-based trackers have drawn amounts of attention in visual tracking field because their excellent performance. However, object on Unmanned Aerial Vehicles platform encounters difficulties under circumstances such as small objects and similar interference. Most existing methods for aerial adopt deeper networks or inefficient policies to promote performance, but most can hardly me...
