It is unique spy robot circuit which can be controlled by using a computer system from its keyboard. It can act as a live telecast of audio and video information’s from the surroundings and can be sent to a remote station through RF signals & also able to access information when surrounding have darkness because its include extra circuitry arrangement which detect darkness and automatically swi...

A four-polarisation camera was used to map the absorbance of olivine micro-grains before and after high-temperature annealing (HTA). It is shown that HTA xenoliths at above 1200 °C in O2 flow makes them magnetised. Different modes operation polariscope with polarisation control sample transmission reflection were used. The type assembled for non-transparent samples HTA. optical observation plac...

Although capturing and displaying stereo 3D content is now commonplace, information-rich light-field video content capture, transmission and display are much more challenging, resulting in at least one order of magnitude increase in complexity even in the simplest cases. We present an end-to-end system capable of capturing and real-time displaying of high-quality light-field video content on va...

RGB-Depth (or RGB-D) cameras are increasingly being adopted for real-world applications, especially in areas of healthcare and athome monitoring. As for any other sensor, and since the manufacturer’s parameters (e.g., focal length) might change between models, calibration is necessary to increase the camera’s sensing accuracy. In this paper, we present a novel RGB-D camera-calibration algorithm...

This paper presents an automatic method for creating a collage from a collection of photos of a scene taken from different viewpoints. The collage is constructed by aligning the images (in terms of their positions, rotations and scales) using a least-squares formulation. We have developed a graph-based optimization algorithm for layering the images so as to minimize the fragmentation of the col...

AIMS To quantitatively analyse cone photoreceptor matrices on images captured on an adaptive optics (AO) camera and assess their correlation to well-established parameters in the retinal histology literature. METHODS High resolution retinal images were acquired from 10 healthy subjects, aged 20-35 years old, using an AO camera (rtx1, Imagine Eyes, France). Left eye images were captured at 5° ...

This paper presents a technique to linearly calibrate a fisheye camera using the fact that the distortion is in the radial direction (angle preservation on the X-Y plane). First, a linear equation based on this constraint is proposed for estimating intrinsic/extrinsic parameters. The skewness in the intrinsic parameters is assumed to be zero in this paper. Second, a pure rotation for the fishey...

The attempts to count the passing people by the image processing have been made some time ago. But the conventional methods could not count the passing people accurately unless there were very few of the passing people through the gate at one time. In this paper, we propose an automatic method of counting the passing people by using the mathed of the template matching process. In proposed metho...

This paper addresses the problem of obstacle detection for mobile robots, using visual information provided by a single on-board camera, as the input. The method proposed, assumes that the robot is moving on a planar pavement, and any point lying outside this plane is considered to be an obstacle. The problem of obstacle detection is addressed by exploiting the geometric arrangement between the...
