What is jpeg image compression?

THE JPEG STANDARD  JPEG is an image compression standard.  It was developed by “Joint Photographic Experts Group”.  JPEG is a lossy image compression method.  It employs transform coding method using the DCT (Discrete Cosine Transform).  JPEG was formally accepted as an international standard in 1992. 5.

What is the history of image compression?

An important development in image data compression was the discrete cosine transform (DCT), a lossy compression technique first proposed by Nasir Ahmed in 1972. DCT compression became the basis for JPEG, which was introduced by the Joint Photographic Experts Group (JPEG) in 1992.

What are the basic parts of jpeg compression system?

Figure 2 describes the basic parts of a JPEG compression system. The color image (which is represented by three basic color images Red, Green, and Blue) are transformed into the equivalent luminance and chrominance images (Y, U, and V), using the transform formular as shown in the previous section.
