A simple and efficient locally linear regression (LLR) method which generates the virtual frontal view from a given nonfrontal face image is presented.

A study proposes a compact and effective object descriptor method, histogram of Gabor phase pattern (HGPP), for robust face recognition. This method is applied to the face recognition problem and the results on the large-scale FERET and CAS-PEAL databases have shown that the proposed algorithms have outperformed other well-known systems in terms of recognition rate.

Automatic detection and recognition of signs from natural scenes and its application to a sign translation task are discussed. The procedure can improve text detection rate and optical character recognition (OCR) accuracy.

The factors inducing neutrophils to change angiotensin-converting enzyme (ACE) activity in cultured pulmonary endothelial cells were studied. It was observed that neutrophils mediate endothelial ACE dysfunction through factors that resemble those influencing cell lysis and augmented permeability. A model for the evaluation of neutrophil-mediated endothelial cell damage in the early stages was developed. It was concluded that polymorphonuclear leukocytes (PMN)-mediated ACE dysfunction may be caused by the synthesis of hydrogen peroxide by PMN, and its subsequent change to hydroxyl radicals.
