Computer Vision Syndrome (CVS) Abstract: Computers are being used for many different reasons all across the world. Computers are used in the work place for documentation and to keep records of clients. The question that will be answered is how does the computer monitor affect an individual during use? The anatomy of the human eye will be addressed to give the reader a better understanding of how light travels through the eye. Computer Vision Syndrome, also known as (CVS), is an effect of gazing
Sign language is a language for the people who are challenging in hearing and listening. Despite common misconceptions, sign languages are complete natural languages, with their own syntax and grammar. 1.1 Problem Statement: There is need of a system in which they can communicate directly with everyone. In such a system, a signer can make a sign and the other person can understand. In that system the input will be sign and corresponding output will be speech. It will use sign to text then text
(2-2) Fourier transform in two Dimensions The Fourier transform is a fundamental importance to image processing . It is a representation of an image as a sum of complex exponentials of varying magnitudes, frequencies, and phases . It plays a critical role in a broad range of image processing applications , including enhancement , analysis , restoration , and compression. Optics generally involves two-dimensional signals ; for example , the field across an aperture or the flux-density
Image shape matching is prime concern in object recognition and identification methods. An image matching is a means of determining the resemblance of one image with the other image. Images are matched based on their shape and texture and it finds variety of applications ranging from image retrieval, object recognition, remote sensing, image classification, image analysis and so on. In general, image matching techniques are classified into structure- based [1] [2] and feature-based [3][4] methods
DESCRIPTION Video editing is the process of combining video footage from two or more recordings with audio from a recording system, and other images and audio files. It also includes adding text, animations, and graphics to a motion picture sequence to produce a single or series of motion pictures which can be viewed as a single concise presentation. PREPARATORY WORK Video editing requires that you have video footage that is to be edited. Place the video footage, audio files, and other resources

Computer vision is a discipline that studies how to reconstruct, interpret and understand a 3D scene from its 2D images in terms of the properties of the structures present in the scene. It combines the knowledge from computer science, electrical engineering, mathematics, physiology, biology and cognitive science in order to understand and simulate the operation of the human vision system. As a scientific discipline, computer vision is concerned with the theory behind artificial systems that extract
*Lunagariya, Jaydeep CECS-553 Machine Vision Spring 2014 Project Description Many computer vision applications provide vast knowledge about the line in an image. Manually extraction of the line information from an image can be very exhausting and time-consuming; especially there are many lines in the image. An automatic method is desirable, but it is not as trivial as edge detection since if any, one has to detect which edge points belongs to which line. The Hough-transform is more preferable to
local changes in the image intensity edge typically occur on the boundary between two regions. The main features are extracted from the edges of an image. Edge detection has major features for image analysis. These features are used by advanced computer vision algorithm. Edge detection is used for object detection which serves various applications like medical image processing, biometrics
Image segmentation divides a digital image into multiple regions in order to analyze them. It is also used to distinguish different objects in the image. Several image segmentation techniques have been developed by the researchers in order to make images smooth and easy to evaluate. Famous techniques of image segmentation which are still being used by the researchers are Edge Detection, Threshold, Histogram, Region based methods, and Watershed Transformation. There are two types of images i.e. gray
CHAPTER III COLOR DESCRIPTION AND EXTRACTION 3.1 INTRODUCTION Image retrieval is the process of handling large volume of image database in order to achieve the efficiency in identifying similar images over the retrieved results. In Image retrieval, a choice of various techniques is used to represent images for searching, indexing and retrieval with either supervised or unsupervised learning models. The color feature extraction process consists of two parts: grid based representative of color selection
Document Image Analysis has today become an increasingly important domain due to the de- sire to reduce the amount of paper documents and archives. Optical Character Recognition (OCR) systems and document structure analyzers are the essential tools to achieve this task. It often appears that the document to be recognized is not correctly placed on the flat-bed scanner, especially when the document comes from a book or a magazine. This results in a skewed digitalized image which is a real problem
tip of their finger. Machine learning is virtually utilized everywhere: homes, businesses, and schools. As a result, machine learning has created a sense of ease toward people’s daily interactions. The main purpose of machine learning is for a computer to predict future trends by analyzing big data. Big data is everywhere within today’s society. We have so much data within our society that we don’t know how to evaluate it. As Stephen Marsland states in his
financial damage, and the possibility of losing my mom's or my own life, could have been prevented if the car behind us was a driverless car. Briefly, a driverless car is capable of driving itself via an intricate system of cameras, sensors and computers. I propose that human drivers should be replaced with driverless cars because driverless cars are safer and more efficient. One reason driverless cars should replace human drivers is because they are safer and offer a comprehensive solution to a
DIGITAL IMAGE PROCESSING Abstract This paper describes the basic technological blee of Digital Image Processing . Image processing is basically classified in to three categories: The Rectification and Restoration, Enhancement and Information Extraction. The Rectification deals with incipient processing of raw image data to correct for geometric distortion, to calibrate the data radiometrically and to eliminate noise present in the data. The enhancement procedures are applied to image data in order
3.0 Methodology The figure 3.1 below shown the overall general workflow of the face emotion recognition system and OpenCV will be applied through the whole process. Figure 3.1 General flow of the system This project will mainly focus on face detection and feature extraction and only one webcam will be used and mounted on a laptop so that the image frame can be extracted out from the video. After we get the image, we will proceed to another stage which is face detection to detect the human face
3.4.1 Color feature extraction Color moments are the measures that describe the color distribution of an image and the central moments are used to describe a probability distribution. Main purpose of color moment is to form the color indexing for image retrieval applications. The color moments are invariant for scaling and rotation. Here, the first three order moments are used as features for image retrieval. Three color moments are calculated for each channel. For example, 9 color moments are
Chapter 2 Segmentation 2.1 OVERVIEW The eye conatins two concentric cirles , the iris/sclera boundary and the iris/pupil boundary. The objective is to isolate the actual iris region from the rest of the image. The image may contan some Noise and the same could be occuluded due to eye lashes and eyelids. So in this step we have to excude these interfrences corrupting the image and determine the circular iris region. The results may depend upon the quality of the image. The database used can have pecuilaiar

Instead of helping them one way or another, technology has affected them negatively. Computer Vision Syndrome is one example that illustrates how technology affects people's bodies. The American Optometric Association define Computer Vision Syndrome as, a group of eye and vision-related problems that result from extended computer use. Many individuals experience eye discomfort and vision problems when viewing a computer screen for long periods 2014). While many people are concerned about the technology
