Jul 10, 2024 · Data compression can be applied to text, pictures, audio and video among other forms of data. This concept involves minimizing redundancies and irrelevances in representing data so that less bytes or bits are required to store or convey it.

Image compression is a process applied to a graphics file to minimize its size in bytes without degrading image quality below an acceptable threshold. By reducing the file size, more images can be stored in a given amount of disk or memory space.

Data compression is the function of presentation layer in OSI reference model. Compression is often used to maximize the use of bandwidth across a network or to optimize disk space when saving data. There are two general types of compression algorithms: 1. Lossless compression. 2. Lossy compression.

Jan 3, 2023 · In this article, we try to explain the overview of the concepts involved in the image compression techniques. The general representation of the image in a computer is like a vector of pixels. Each pixel is represented by a fixed number of bits.

Jul 16, 2024 · Data compression is a technique for reducing data size that can be divided into two categories: lossy and lossless. Lossy compression permanently removes certain data to significantly decrease file size, making it perfect for multimedia but inappropriate for crucial data.

"A wonderful treasure chest of information; spanning a wide range of data compression methods, from simple test compression methods to the use of wavelets in image compression. It is unusual for a text on compression to cover the field so completely." – ACM Computing Reviews.

What else needs compression? Video Textures (diferent requirements than plain images) Geometry (including animations) Anything else?

The processing of a set of data in order to reduce its size. Compression may be performed both to reduce the amount of storage space occupied (say, to fit the data onto a single CD) and to reduce the time it takes to transmit (say, over a slow telephone line).

Aug 21, 2000 · Simply put, compression methods crunch data – text, graphics, audio or video – into a computer-decipherable shorthand that’s 10% to 99% of its original size.
