    PROBLEM DEFINITION Image compression is the art and science of reducing the amount of data required to represent an image. The purpose for image compression is to reduce the amount of data required for representing sampled digital images and therefore reduce the cost for storage and transmission. Image compression plays a key role in many important applications, including image database, image communications, remote sensing. LZW compression, one of the lossless image compression methods and invented

  • Image Compression: The Purpose Of Image Compression

    958 Words  | 2 Pages

    The purpose of image compression is to represent images with less data in order to save storage costs or transmission time. Without compression, file size is significantly larger, usually several megabytes, but with compression it is possible to reduce file size to 10 percent from the original without noticeable loss in quality. Image compression can be lossless or lossy. Lossless compression means that you are able to reconstruct the exact original data from the compressed data. Image quality is not

  • Advantages And Disadvantages Of Digital Compression And Digital Image Processing

    1296 Words  | 3 Pages

    1 INTRODUCTION An image as perceived in "reality" is thought to be a function of two real variables, for instance, a(x, y) with a certain level of brightness of the image at the real coordinates (x, y). Further, an image may be considered to contain sub-images now and mentioned to as areas of-investment or ROI’s, or basically regions. This idea reflects the way that images as often as possible contain build-ups of items each of which can be the idea for a region. Digital image processing is the

    grand prophecies? Primarily, two technological advances known as digitization (including digital compression), and fibre optics. Both are indispensable to the high-speed networks that will deliver dynamic new services to homes and offices. Digitization means translating information, either video, audio, or text, into ones and zeros, which make it easier to send, store, and manipulate. Compression squeezes this information so that more of it can be sent using a given amount of transmission capacity

    constants when the springs are in series and in parallel. The theory is based on Hooke's law which is: F = kx where F = Force, k = Constant and x = Extension [Ref. 1]. Unfortunately with the springs I have, I can only measure extension, not compression for which Hooke's is also valid. Prediction Single Spring: Hooke's law, where F = kx. I predict that I if I plot Force on the Y axis and extension, x, on the X axis, it will be a straight line and the gradient will be the spring constant

    concern of bestimmtheit in films. I hope to address certain concerns such as the extent to which a film can "specify" a particular object and what this specification does with regards to our understanding of the text. In addition, I will relate the compression of information into imagery to the limitations of time, given that a short film has a limit of 15 minutes. To do this, I shall analyse the cinematography of the short film, and show how relevant they are in bringing out certain scenarios described

    sections: intake, compressor, diffuser, combustion chamber, turbine, and exhaust. These sections are much like the different cycles in a four-stroke reciprocating engine: intake, compression, power and exhaust. In a four-stroke engine a fuel/air mixture is is brought into the engine (intake), compressed (compression), and finally ignited and pushed out the exhaust (power and exhaust). In it's most basic form, a jet engine works in much the same way. * Air comes in the front of the engine
