3D-Measuring is paid to attention because 3D-Display is making rapid spread. Especially, face and head are required to be measured because of necessary or contents production. However, it is a present problem that it is difficult to measure hair. Then, in this research, it is a purpose to measure face and hair with phase shift method. By using sine images arranged for hair measuring, the problems on hair measuring, dark color and reflection, are settled.
Glucose-6-phosphate dehydrogenase (G6PD) is the key enzyme of the pentose phosphate pathway in carbohydrate metabolism, and it plays an important role in cell proliferation and antioxidant regulation within cells in various organs. Although marked cell proliferation and oxidant/antioxidant metabolism occur in lung alveolar epithelial cells, definite data has been lacking as to whether cytochemically detectable G6PD is present in alveolar epithelial cells. The distribution pattern of G6PD within these cells, if it is present, is also unknown. The purpose of the present study was to investigate the subcellular localization of G6PD in alveolar cells in the rat lung using a newly developed enzyme-cytochemistry (copper-ferro-cyanide) method. Type I cells and stromal endothelia and fibroblasts showed no activities. Electron-dense precipitates indicating G6PD activity were clearly visible in the cytoplasm and on the cytosolic side of the endoplasmic reticulum of type II alveolar epithe-lial cells. The cytochemical controls ensured specific detection of enzyme activity. This enzyme may play a role in airway defense by delivering substances for cell proliferation and antioxidant forces, thus maintaining the airway architecture. 243 Accepted: 2/04/02
We independently have developed low-cost fi nger vein certification device. The light transmission of a finger differs depending on each person so we need automatic light intensity adjustment system to certificate each person. In this paper, we report the automatic system which controls light intensity by fee dback control and it is controlled by intensities of captured images. This adjustment system makes possible to capture stable and high contrasted images which shows any finger veins. Moreover, we have developed two types of fi nger vein certification devices. One is penetrated type and the other is reflection type. The penetrated device shows over 99.91 % 1 certification rate, and the reflection device shows 98.82 [%]. The fo rmer shows high certification accuracy, but the reflection device could be smaller than the penetrated device.
We propose a method of correcting phase distortion which is caused when measuring any objects by phase shifting method with an ordinary projector. We have measured some objects with the projector which is commercially available [1]. In this paper, we try to improve the precision with the proposing method. The method calculates differences between the idealized phase and observed, and then feeding back the error to the observed phase. By using this method, the precision could be made better by 47%.eywords-three dimentional measuring; phase shifting method; projector; precision improvement
Phase Shifting Method, measuring method of three-dimensional shapes, is able to measure by high accuracy in short time.However there are some difficulties to acquire three-dimensional data because of phase unwrapping problem which occurs phase unwrapping errors and makes accuracy worse. Some of techniques have been used for avoiding the problem in the traditional methods. One of the traditional methods combines with space encoding method. This method could be robust and high accurate but requires several gray-code patterns other than phase shifting patterns. This makes measuring time longer. In this paper, we propose a correcting phase unwrapping error method which requires only phase shifting patterns to measure objects. The proposal method corrects over 99 [%] phase unwrapping errors. This result is almost same as the result of the traditional method. Therefore we are able to unwrap phase values as same accuracy as the traditional method by our proposal method despite reducing projecting patterns.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
