Introduction Lateral tape motion (LTM) is the time-dependent displacement of magnetic tape perpendicular to the tape transport direction. Lateral tape motion may cause track misregistration between the read/write head and a previously written track, thereby limiting the recording density that can be achieved [1]. Currently, the track density of typical magnetic tape drives is approximately 40 t...
In this research, we propose an automatic group activity recognition approach by modelling the interdependencies of group activity features over time. Unlike simple human activity recognition, the distinguishing characteristics of group activities are often determined by the way how the movement of people are influenced by one another. We propose to model the group interdependences in both moti...
BACKGROUND AND PURPOSE Super-resolution track density imaging generates anatomic images with submillimeter voxel resolution by using high-angular-resolution diffusion imaging and fiber-tractography. TDI within the diseased human brain has not been previously described. The purpose of this study was to correlate TDI with histopathologic features of GBM. MATERIALS AND METHODS A total of 43 tumo...
Track Orientation Density Imaging (TODI) and Track Orientation Distribution (TOD) based tractography
Ever since the introduction of the concept of fiber tractography, methods to generate better and more plausible tractograms have become available. Many modern methods can handle complex fiber architecture and take on a probabilistic approach to account for different sources of uncertainty. The resulting tractogram from any such method typically represents a finite random sample from a complex d...
