computer screen are made up of a matrix of pixels‚ tiny dots of black‚ white and color arranged in rows. Combination of pixels on the screen outlines the shape of letters‚ images‚ and all visual representations that appear on the computer. When painting‚ or representing an image on the screen there are different approaches of controlling the emerging shape. When free-hand painting is employed where every move form mouse or stylus is captured‚ as each pixel is determined‚ we say we are using bitmapped

In order to determine the mean elevation of the pixels that belong to the roads the following process has been followed. During the LiDAR data collection the route was on the roads surface. Therefore‚ the trajectory line of the ZEB1 LiDAR can be used. This is very important information because it allows

ABSTRACT: Image Processing is processing of the image so as to reveal the inner details of the image for further investigation. With the advent of digital computers‚ Digital Image Processing has started revolutionizing the world with its diverse applications. The field of Image Processing continues‚ as it has since the early 1970’s‚ on a path of dynamic growth in terms of popular and scientific interest and number of commercial applications. Considering the advances in the last 30 years resulting

Background Information The hippocampus is a brain structure that is involved with memory‚ spatial awareness and navigation. For memory‚ the hippocampus is linked to the conversion of information from short-term memory to more permanent memory. From studying a man known as HM‚ we know that the impact of

commonly understood that changes to the LSB of color cannot be detected due to noise that is always presents in digital images. In this paper‚ we describe a new very accurate and reliable method that can detect LSB. Embedding in randomly scattered pixels in both 24-bit color images and 8bit grayscale or color images. The first step is steganography is that to embed and hiding information is to pass both the secret message and the cover message in to the encoder‚ inside the encoder‚ one or several

Liquid Crystal Displays (LCD) – Working We always use devices made up of Liquid Crystal Displays (LCDs) like computers‚ digital watches and also DVD and CD players. They have become very common and have taken a giant leap in the screen industry by clearly replacing the use of Cathode Ray Tubes (CRT). CRT draws more power than LCD and are also bigger and heavier. All of us have seen an LCD‚ but no one knows the exact working of it. Let us take a look at the working of an LCD. We get the definition

frames. We measure the rate at which frames are displayed in frames per second (FPS). Since every frame is an orthogonal bitmap digital image it comprises a raster of pixels. If it has a width of W pixels and a height of H pixels we say that the frame size is WxH. Pixels have only one property‚ their color. The color of a pixel is represented by a fixed amount of bits. The more bits the more subtle variations of colors we can reproduce. This is called the color depth (CD) of the video. An example
