Also, device independent output is useful because the images can be accessed by systems with different resources in bandwidth, storage, and display. For example, progressive transmission is useful for browsing while lossless compression is needed by the best output devices. CREW meets all of these needs with an elegant and powerful compression system. World Wide Web image or graphic type Device independence, progressive transmission, high quality, and open standards are imperative for transmitting and interacting with images across wide area networks. CREW's pyramidal progressive nature and high quality compression make it ideal for the WWW where there are a number of networks and displays with varying capabilities.
CREW allows the application to adapt to the capabilities and desires of the users.
Satellite imagery Satellite images tend to be deep pixel and high resolution. In addition, this application has a limited bandwidth channel. Progressive transmission might be desirable to allow humans to browse or preview images. CREW's features offer this application the flexibility that is needed. Technical contribution Highlights of the CREW technology are introduced below.
