Image compression

All types of data can be compressed, but we will focus on image compression in this presentation. We will review the image processing work flow, show examples of varying degrees of compression of an image, and discuss the question of how much to compress an image We will informally address the amount of information in an image and see that discarding information can lead to visible pixilation. Finally, we'll say why compression is important and we'll differentiate between lossy and lossless compression.

Keywords:: image processing work flow, lossy versus lossless compression, the amount of information in an image, pixilation, matching compression level to your application. compression, visual effect of image compression, the importance of compression
