Image Compression Method 2014 Pdf Data Compression Digital Technology Image compression is a type of data compression applied to digital images, to reduce their cost for storage or transmission. algorithms may take advantage of visual perception and the statistical properties of image data to provide superior results compared with generic data compression methods which are used for other digital data. Image compression is a process that minimizes the size of graphics file to an acceptable point. learn about two compression methods: lossy and lossless.
Lecture10 Image Compression Pdf Data Compression Information Image compression is the process of making image files smaller. learn more about the algorithms and techniques used to compress images. Image compression basics basic strategy in image compression ideally, an image compression technique removes redundant and or irrelevant information, and efficiently encodes what remains. practically, it is often necessary to throw away both non redundant information and relevant information to achieve the required compression. The basics of image compression at its core, image compression works by identifying and eliminating redundant or unnecessary data in image files. digital images contain millions of pixels, each defined by specific color values that require storage space. compression algorithms analyze these patterns of information and find clever ways to represent the same visual data using fewer bytes. Gif: the basics graphics interchange format one of the earliest developed image compression algorithms (1987) limited to 8 bit color space each gif image can contain only up to 256 different colors selected from a 24 bit rgb color space uniquely supports animations based on lzw compression scheme.

Abstract because of the explosively increasing information of image and video in various storage devices and internet, the image and video compression technique becomes more and more important. this paper introduces the basic concept of data compression which is applied to modern image and video compression techniques such as jpeg, mpeg, mpeg 4 and so on. By understanding these algorithms, you can select the right compression technique based on your image’s complexity and desired balance between file size and quality.
