Face recognition in photographic positive and negative was examined in a same/different matching task in five lighting direction conditions using untextured 3-D laser-scanned faces. The lighting directions were +60, +30, 0, -30 and -60 degrees, where negative values represent bottom lighting and positive values represent top lighting. Recognition performance was better for faces in positive tha...

rural tourism is considered as one of the important parts of the economic activities. this important economic activity in the different views has been taken into consideration. some know it as a part of the tourism market and some consider it as a policy for rural development. rural tourism quickly grew in the rural economic and has been the complementary of agricultural activities. the nature ...

Illumination variation is one of intractable yet crucial problems in face recognition and many lighting normalization approaches have been proposed in the past decades. Nevertheless, most of them preprocess all the face images in the same way thus without considering the specific lighting in each face image. In this paper, we propose a lighting aware preprocessing (LAP) method, which performs a...

Orbital injuries with a foreign body may result in severe structural and functional damage to the eye or orbital contents. The clinical presentation of an orbital foreign body is variable. Management and prognosis depend on the composition, location of the object and presence or absence of secondary infection. Metallic objects and glass particle foreign bodies are the most frequently encountere...

Despite the technical advances in radiological imaging modalities that have occurred in recent years in detecting foreign bodies like wood and plastics, they are not very often relied upon. Five of the six cases reported below seen over a period of 6 months, had a delayed presentation and ultrasound was found to be very useful in detecting and planning the treatment. The author strongly recomme...

68 October 2007 EngineerIT This article aims to automate such intuitive human skills for future sleeper inspections. Pattern recognition has been proposed for classification and results from sensors based on the abovementioned methods were fused to generate a single output condition. Final results achieved in this work indicate an overall classification rate of around 88% compared to the human ...

Automatic lighting design aims to provide users with semi-automated approaches, and easy-to-use tools, to configure lighting for 3D scenes. We present LIGHTOPEX the first fully automatic example-based local illumination lighting design system. Utilizing a wavelet-based lighting design framework, by which image quality is modeled using a cognitively inspired objective function, this approach to ...

Wood, acting as a construction material, has been utilized by humans since the beginning of times. The early human-made machines were made entirely from wood. With time, technical progress gradually displaced wood machine design and construction. However, despite passage due to low cost availability wood, elements in quickly worn out parts still Sliding bearing shells or replaceable gear teeth ...
