conclusion to which of these suit certain graphical products. Adding on from this report, I will compare the limitations of hardware/software where I will select two graphic-related hardware devices and compare their limitations - the limitations of raster will also be compared. With the final point adding, I will

Impact that file format, compression techniques, image resolution and colour depth have on file size and image quality - D2 In this report I will be discussing the different file formats, compression techniques, image resolution and colour depth. I will be explaining the different purposes, then, after I have issued an in-depth explanation of image quality and file size I will be completing a final conclusion about the best ones to use for certain tasks. Seen as there are numerous different uses

I have been working with Adobe Photoshop and Adobe Illustrator since October of last year and noticed that there were some things that I could do with one program and not with the other. I was a bit curious about it and the thought that rose in my mind was what is the difference and similarity of the two Programs. I often use them hand and hand, knowing that they really compliment the work of each other. So with that question in mind, I decided to do a little research on the Adobe Illustrator and

of the background image and maybe the quality of the background image as it may lead to longer load times and so the background should be properly optimised. For a background image the designer can use a raster image say if the background was the badge of a car or an image of a sports car. Raster images are good for displaying detailed images their quality is lost when they are zoomed in. This is an example of a bad website background: This is an example of an appealing background for a web site:

Bitmap -- Vector What are they? How are they different? Problems if it is made bigger or smaller(scaling) Example When are they used Advantages and disadvantages of each. Optical illusion of motion: This is an illusion that affects your eyes that when a number of still images are played one after the other at a fast rate we perceive as one object that is moving in the image and this is due to persistence of vision which is a term used to describe the Eye not being able to see the stops

In the presently highly digital world we live in, there are essentially two types of graphic “files” used, the bitmap and the vector graphics. Both have an overall similar principal but differ in various sub-arrays, which bring along each of their own advantages and disadvantages. To begin with, the word bitmap originated in the year 1973, and came to be by adding the words bit + map which literally means a map of bits, which perfectly describes the nature of a bitmap graphic. A bitmap is composed

LINE CLIPPING ALGORITHMS Line clipping is the process of removing lines/portions of lines that are outside of an area of interest. There are two main algorithms of line clipping namely: 1) Copen- Sutherland 2) Liang Barsky Copen – Sutherland This algorithm is used to detect and dispense with two trivial cases and in order to clip a line we are required to consider only the end points. When the endpoints of a specific line lie inside the window then it can be said to be trivially accepted and clipping

Biometric Scan Technologies Abstract At present day’s usage of computers, laptops, mobile phones and security systems increasing day by day. In order to protect the data from unauthorized access authentication is necessary. The most common methodology used for authentication are passwords and passcodes which has some disadvantages. To overcome the disadvantages of Passwords and Passcodes, Biometric Scan Technologies are introduced. Biometric scan Technologies are most advanced and reliable authentication

revolutionize the policing. If we step back on the history, the twentieth century saw fingerprinting become an invaluable forensic tool, such as iris pattern-matching or facial recognition could have an equal success on the 21st century policing (Retinal Scan). The limitations certainly apply to biometrics. Some reports suggest that recognition error rates can be as high as ten per cent. No single biometric system guarantees coverage of the entire population, but in the Muslim woman’s case this could
