Morphologic filters are used here to interpolate missing values from sets of frequency domain measurements, as occurs in Magnetic Resonance Imaging. MRI data acquisition is done in the Fourier domain which is often sub-sampled to reduce the required scan time. Partial recovery of the missing frequency samples permits direct Fourier inversion to provide a rapid and improved initial estimation of the...
Recent research in tomographic reconstruction is motivated by the need to efficiently recover detailed anatomy from limited measurements. One of the ways to compensate for the increasingly sparse sets of measurements is to exploit the information from \emph{templates}, i.e., prior data available in the form of already reconstructed, structurally similar images. Towards this, previous work has exploited...
We have developed a system for analysing hand tremors using a deformable object manipulation in a haptic environment. The subject performs some specific manipulative tasks, like moving a soft object from one location to another, in a virtual 3D environment using a haptic device. While the task is being performed, the velocity of hand movement is sampled by the haptic device and this is later processed...
