Blind people use echoes to detect objects and to find their way, the ability being known as human echolocation. Previous research have found some of the favorable conditions for the detection of the object, with many factors yet to be analyzed and quantified. Studies have also shown that blind people are more efficient than the sighted in echolocating, with the performance varying among the ind...

In this paper we present a multi-pedestrian detection and tracking framework targeting a specific application: detecting vulnerable road users in a truck’s blind spot zone. Research indicates that existing non-vision based safety solutions are not able to handle this problem completely. Therefore we aim to develop an active safety system which warns the truck driver if pedestrians are present i...

Adaptive neuroplastic changes have been well documented in congenitally blind individuals for the processing of tactile and auditory information. By contrast, very few studies have investigated olfactory processing in the absence of vision. There is ample evidence that the olfactory system is highly plastic and that blind individuals rely more on their sense of smell than the sighted do. The ol...

In wideband direct sequence code division multiple access (W-CDMA) mobile radio, variable-rate data (VRD) services are supported to increase the link capacity. To recover VRD at a receiver, a cyclic redundancy check (CRC)-based blind rate detection scheme was proposed that does not require the transmission of any additional information. This paper proposes a modified CRC-based blind rate detect...

Cognitive radio has been attracting increased attention as an effective approach to improving spectrum efficiency. One component of cognitive radio, spectrum sensing, has an important relationship with the performance of cognitive radio. In this paper, after a summary and analysis of the existing spectrum-sensing algorithms, we report that the existing eigenvalue-based semi-blind detection algo...

To help blind people overcoming difficulty in their movement the physical environment and even home, a study on an engineering concept is very much necessary. So, our research comes out with aid that will surroundings. It can detect any obstacle block path of blind. And The motion user be sensed by bot. Thus, Blind comfortably receive bot assisting from one place to another. This paper describe...

PURPOSE We investigated whether people with homonymous hemianopia (HH) were able to spontaneously (without training or instructions) adapt their blind-side scan magnitudes in response to differing scanning requirements for detection of pedestrians in a driving simulator when differing cues about pedestrian eccentricities and movement behaviors were available in the seeing hemifield. METHODS T...

Among the many techniques available for information concealment, those based on spread spectrum modulations have proven to yield improved results when robustness against attack is at a premium. In this paper, we propose a new spread spectrum-based watermarking procedure that combines space and frequency marks to provide good robustness properties against both spatial (affine) and transform-base...
