Image mosaicing is commonly used to increase the visual field of view by pasting together many images or video frames. Existing mosaicing methods are based on projecting all images onto a pre-determined single manifold: a plane is commonly used for a camera translating sideways, a cylinder is used for a panning camera, and a sphere is used for a camera which is both panning and tilting. While d...

In the last decade new actuator designs have been presented trying to introduce at mechanical level the advantages of compliance. Ranging from serial elastic actuators to different designs of variable stiffness actuators, various prototypes have been proposed and implemented on robots, thus allowing performance of novel and challenging tasks. Nevertheless some of these new devices often are aff...

We introduce iOwe, a deferred compensation scheme that can be used in a broad range of decentralized systems. iOwe is reminiscent of a currency scheme backed by a precious commodity: network resources. iOwe does not require a central authority, proofs of work, continuous connectivity to currency issuers, or trusted storage. Instead, in iOwe, any principal may issue their own currency, in any am...

This paper studied the method for motion tracking of arm using triaxial accelerometer, triaxial gyroscope and electronic compass. The motion model of arm is established. The hardware of tracking system of arm is designed. The track method of arm gesture based on multi-sensors data fusion is analyzed. The compensation algorithm for motion accelerations is researched. The experimental results dem...

Radar imaging of noncooperative targets is an interesting application of all-weather high-resolution coherent radars. However, these images are usually blurred when using the standard range-Doppler algorithm, if a long coherent processing interval (CPI) is used, and motion compensation techniques are hence necessary to improve imaging quality. If the CPI is reduced enough, target scatterers do ...

Stiction is one of the most adverse non-linearities that can affect a control valve. It impacts both valve longevity and product quality. Currently available stiction compensation methods either reduce the amplitude of oscillation at a cost of increased frequency or require knowledge about process and valve models. In this study a novel stiction compensation scheme is developed which reduces bo...

Medical ultrasound images are an important diagnostic tool for physicians, but suffer from low image intensity, dropouts, and noise in the form of speckle. I propose a new method for ltering ultrasound image sequences which is based on a motion-compensated temporal lter. The key contribution is a new method for detecting and tracking image features which is fully automatic. Applying this algori...
