This paper proposes a method for obtaining surface ori-entations of transparent objects using polarization in highlight. Since the highlight, the specular component of reflection light from objects, is observed only near the spec-ular direction, it appears merely limited parts on an object surface. In order to obtain orientations of a whole object surface,(More)
A method is proposed for obtaining surface orientations of transparent objects by use of polarization in highlight. Since the highlight, the specular component of light reflected from objects, is observed only near the specular direction, it reveals only limited parts of an object's surface. To obtain the orientations of the whole surface of an object, we(More)
The effects of sub-solubilizing concentrations of sodium cholate (Na-chol) on several physicochemical properties of phosphatidylcholine (PC) small unilamellar vesicles (SUV) were considered in connection with the initial stage of membrane solubilization. ESR spectra of 12-doxylstearic acid (12-DS) in phosphatidylcholine from egg yolk (EPC) or(More)
|This paper describes a method for vehicle recognition , in particular, for recognizing a vehicle's make and model. Our system is designed to take into account the fact that vehicles of the same make and model number come in dierent colors; to deal with this problem, our system employs infra-red images, thereby eliminating color dier-ences. Another reason(More)
Subtotally nephrectomized rats were found to have decreased activities of superoxide dismutase (SOD) and catalase, and spin trapping with 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) showed that the amount of hydroxyl radical in the residual kidney tissue was greater than that in normal rat kidney. This indicated both direct and indirect involvement of free(More)
