Description
Lossy compression will permanently discard data. What is necessary is to determine – for any given object, set of objects, or purpose – what information is actually useful and necessary to retain. We already balance these decisions at the capture stage. Choosing to use a small-format camera immediately limits the amount of information that can be detected by the camera sensor. Choosing one lens over another introduces a slightly different distortion. Compression also represents a choice between what you can capture and what you actually need. One may not need all the information that has been captured; some of it may be redundant. A lot of it may be redundant. And the point of JPEG 2000 is that it is very good at removing redundant information.
