In this paper, a development of image processing, stereovision methodology and a sonification procedure for image sonification system for vision substitution are presented. The hardware part consists of a sunglass fitted with two mini cameras, laptop computer and stereo earphones. The image of the scene in front of blind people is captured by stereo cameras. The captured image is processed to e...

Navigation Assistance for Visually Impaired (NAVI) is a vision substitute system designed to assist blind people for autonomous navigation. NAVI working concept is based on ‘image to sound’ conversion. The vision sensor, which is mounted on a sunglass, captures the image infront of blind user. NAVI processing unit processes the captured image and enhances the significant vision data by employin...

In this work, we conducted downward evacuation experiments in four types of staircases under various smoke visibility conditions the naked eye, wearing sunglass and eyeshades. Ten male ten female college students were recruited to conduct as a single male, female, two males supporting one another, females another carrying on his back. The time each floor was recorded. corresponding models estab...

As is needless to say; a majority of accidents, which occur, are due to drunk driving. As such, there is no effective mechanism to prevent this. Here we have designed an integrated system for the same purpose. Alcohol content in the driver’s body is detected by means of an infrared breath analyzer placed at the steering wheel. An infrared cell directs infrared energy through the sample and any ...

The paper proposes a method for robust face recognition from low quality Kinect acquired images which have a wide range of variations in head pose, illumination, facial expressions, sunglass disguise and occlusions by hand. Multiple Kinect images of a person are considered as an image set and face recognition from these images is formulated as an RGB-D image set classification problem. The Kine...

A means and apparatus for covert capture of extremely high-resolution photorealistic images is presented. The apparatus embodies a new form of user-interface – instead of the traditional “point and click” metaphor which was thought to be the simplest photography had to offer, what is proposed is a “look” metaphor in which images are generated through the natural process of looking around, in a ...

PURPOSE Anecdotal evidence suggests that some sunglass users prefer yellow tints for outdoor activities, such as driving, and research has suggested that such tints improve the apparent contrast and brightness of real-world objects. The aim of this study was to establish whether yellow filters resulted in objective improvements in performance for visual tasks relevant to driving. METHODS Resp...

BACKGROUND/PURPOSE Cumulative sunlight exposure and cataract surgery are reported risk factors for advanced age-related macular degeneration (AMD). Laboratory studies suggest that accumulation and photochemical reactions of A2E (N-retinylidene-N-retinylethanolamine) and its epoxides, components of lipofuscin, are important in AMD. To relate this data to the clinical setting, we modeled the effe...

In web information retrieval, the interpretation of text is crucial. In this paper, we describe an approach to ease the interpretation of compound word (i.e. words that consist of other words such as “handshake” or “blackboard”). We argue that in the web information retrieval domain, a fast decomposition of those words is necessary and a way to split as many words as possible, while we believe ...
