Optical flow is a highly researched area in low-level computer vision. It is a complex problem which tries to solve a 2D search in continuous space, while the input data is 2D discrete data. Furthermore, the latest representations of optical flow use Hue-Saturation-Value (HSV) colour circles, to effectively convey direction and magnitude of vectors. The major assumption in most optical flow app...
Introduction: Recent development of methods to measure p0, in the clinic has generated data confirming a prognostic relationship between tumor p0, and clinical outcome. These results provide a powerful stimulus for development of enhanced methods for monitoring tumor ~0,. We have been developing a methodFRBDOM (Fluorine Relaxometry using Echo planar imaging for Dynamic Oxygen Mapping), which ty...
Barium ferrite thin films with perpendicular magnetic anisotropy have been prepared on heated (001) sapphire substrates by laser ablation deposition in an oxygen atmosphere using a KrF excimer laser. X-ray diffraction patterns reveal highly oriented films of the magnetoplumbite phase with a c-axis angular spread of 1.8”. Scanning electron micrographs reveal that these films are polycrystalline ...
The technique of velocity modulation spectroscopy has recently been combined with cavity enhancement and frequency modulation methods into a technique called noise-immune cavity-enhanced optical heterodyne velocity modulation spectroscopy (NICE-OHVMS). We have implemented NICE-OHVMS with a cw-optical parametric oscillator (OPO) tunable from 3.2 to 3.9 lm, and used it to record spectra of the R(...
All optical signal level swapping and multilevel amplitude noise mitigation are experimentally demonstrated using the three gain regions of optical parametric amplification, i.e., linear, saturation, and inversion. The two-amplitude-shift-keying and eight-quadrature-amplitude-modulation optical communication systems with baud rates of both 10 and 20 Gbaud have been employed to demonstrate the p...
