In this paper, the illumination problem of face recognition is investigated. A conclusion is drawn that the logarithm vertical gradient (LVG) of face images is more robust to varying lighting than the logarithm horizontal gradient (LHG). When the variation of illumination is large, LVG will be a better representation of the face image than logarithm gradient (LG). Although both LVG and LHG can ...
The growth of the maxillary complex of 36 rhesus monkeys (Macaca mulatta) was analyzed quantitatively and qualitatively during four defined stages of postnatal development (i.e., infant, juvenile, adolescent, young adult). At each stage, growth was observed during a 24 week period. Since some animals were observed during two successive stages of development, 47 periods of growth were studied. T...
We injected botulinum toxin into the horizontal rectus muscles of the right eyes of 2 patients who had acquired pendular nystagmus with horizontal, vertical, and torsional components. This treatment successfully abolished the horizontal component of the nystagmus in the injected eye in both patients for approximately 2 months. Both patients showed a small but measurable improvement of vision in...
