Digital Image and Video Compression Techniques
Internet is very essential for any form of communication. The average net user and communicated through text, images and videos, of these the simplest and easiest is through text as it is quick as simple to use as sending text very little bandwidth. The problem with images and videos is that they require large bandwidth the send and receive. Therefore, there is a need to decrease the size of th...
متن کاملDigital Image Compression
When several gray midtones are present, like a black and white photo, two values are no longer sufficient to encode all the possible gray intensities, and to each pixel must be associated a numerical value, proportional to the brightness of that point. Typical choices for these values fall in the ranges 0 31 or 0 255 (requiring respectively 4 and 8 bits for each pixel). This second kind of imag...
متن کاملFractal Image Compression Techniques
Image compression is an essential technology in multimedia and digital communication fields. Fractal image compression is a potential image compression scheme due to its potential high compression ratio, fast decompression and multi resolution properties. Fractal image compression utilizes the existence of self symmetry of images. Since Bransley gave the concept of fractal image compression in ...
متن کاملImage Compression Techniques
Digital images required large number of bits to represent them and in their canonical representation, generally contain significant amount of redundancy. Image compression techniques reduce the number of bits required to represent an image by taking advantage of these redundancies.To overcome this redundancy several image compression techniques are discussed in this paper along with their benef...
متن کاملImage Compression Techniques: A Survey
The increasing attractiveness and trust on digital photography has given rise to its use for visual communication. It requires storage of large quantities of data. Due to limited bandwidth and storage capacity, images must be compressed before storing and transmitting. Many techniques are available for compressing the images. But in some cases these techniques will reduce the quality and origin...
