Trust me, if you are into robotics, you are going to enjoy the next few pages. After all, making â€Å"a robot that can see† would really be cool! So let’s get started! A vision based robot has an image acquisition device like a webcam as its eyes. Then we need a processor that can make sense out of those captured images and actuators like dc motors for navigation. One key point to note is that Image Processing has huge computational requirements, and it is not possible to run an image processing code directly on a small microcontroller. Hence, for our purpose, the simplest approach would be to run the code on a computer, which has a webcam connected to it to take the images, and the robot is controlled by the computer via serial or parallel port. The code is written in a software that provides the tools for acquiring images, analyzing the content in the images and deriving conclusions. MATLAB is one of the many such software available which provide the platform for performing these tasks. MATLAB What does MATLAB stand for? MATLAB stands for MATrixShow MoreRelatedImage Processing And Image Enhancement1418 Words   |  6 PagesAbstract Image enhancement is to process an image, in order to make the result more suitable than original image for specific application. i.e. the image is enhanced.For that many image enhancement techniques are used. Appropriate choice of such techniques is very important.Image Enhancement is simple and it’s the area based on digital image processing techniques. It improves the quality of the images by working with the existing data. Keywords: Image processing, Image enhancement 1. IntroductionRead MoreImage Processing Essay1097 Words   |  5 Pageslatency is going up. As we cannot measure everything with a scale or a tape, we use some optical methods of Image Processing. In this paper, we present an approach that can be used to determine the lengths and some other degrees of measurements like diameter, spline, Caliper(perpendicular angle) etc. We used mostly the Image Processing techniques because all the measurements are done on an Image. We also use some other techniques like Euclidean algorithm. Index Terms: - Spline, Euclidean algorithm,Read MoreThe Image Of Image Processing1224 Words   |  5 PagesINTRODUCTION 1.1. Introduction to broad area of research Image processing: Image processing is a methodology to perform some operations on an image, so as to urge an enhanced image or to extract some helpful data from it. It is treated as an area of signal processing where both the input and output signals are images. Images are portrayed as two dimensional matrix, and we are applying already having signal processing strategies to input matrix. Images processing finds applications in several fields like photographyRead MoreOptical And Analog Image Processing752 Words   |  4 Pagesscience, image processing is processing of images using mathematical operations by using any conformation of signal processing for which the input is an image, such as a picture or video frame, the out turn of image processing may be either an image or a set of features or parameters corrsponding to the image.Most image-processing techniques implicate treating the image as a 2D signal and appealing worth signal-processing techniques to it. Image processing usually refers to digital image processing, butRead MoreImage Processing : Edge Detection1392 Words   |  6 Pages IMAGE PROCESSING ? EDGE DETECTION In image processing, Edge Detection is a fundamental tool based on mathematical methods to detect points in a digital image at which there is a huge variation in the brightness between each other. These points are organized in a line of segments which is called edges. The purpose of detecting those variations is to help analyze an image in the following aspects: discontinuities in depth? discontinuities in surface orientation? changes in material propertiesRead MoreTaking a Look at Image Processing3018 Words   |  12 Pages Image Processing is a technique to enhance raw images received from cameras/sensors placed on satellites, space probes and aircrafts or pictures taken in normal day-today life for various applications. Various techniques have been developed in Image Processing during the last four to five decades. Most of the techniques are developed for enhancing images obtained from unmanned spacecrafts, space probes and military reconnaissance flights. Image Processing systems are becoming popular dueRead MoreData Processing : Image Processing1627 Words   |  7 PagesIntroduction to broad area of research 1.1.1.

These operations are performed so that enhanced image can be obtained from the original image or we can extract some useful information from the original image. The image processing is a type of signal dispensation in which the input is an image which is usually in the form of video frames, photograph etc. The output of the image processing can be imageRead MoreFeature Extraction : The Third Stage Of Medical Image Processing Application, After Image Pre Processing1268 Words   |  6 PagesFEATURE EXTRACTION Feature extraction is the third stage in medical image processing application, after image pre-processing. In feature extraction, the features like the shape, colour, texture are used to describe an image content[bio2].features can be short relevance or strong relevant ones. Short relevant features give only little information about the image, while strong relevant features provide significant information about the image. Finding these strong relevant features are time consuming andRead MoreThe Image Processing Techniques For Breast Cancer1513 Words   |  7 PagesAbstract- In recent years the image processing techniques are used commonly in various medical areas for improving earlier detection and treatment stages, in which the time span or elapse is very important to discover the disease in the patient as possible as fast, especially in many tumours such as the lung cancer, breast cancer. This system generally first segments the area of interest (lung) and then analyses the separa tely obtained area for nodule detection in order to examine the disease. Even
