In this paper, a efficient method of „Image Search‟, is proposed to find the most similar images for the given query image from the image Repository in which we first pre-process the original image based on different image features like edge, saturation, hue, brightness, luminance and then we will perform some similarity test on each features set of images and then find image according to the g...

In an information-rich Virtual Reality (vr) environment , the user is immersed in a world containing many objects providing that information. Given the-nite computational resources of any computer system, optimization is required to ensure that the most important information is presented to the user as clearly as possible and in a timely fashion. In particular, what is desired are means whereby...
