Abstract
This paper describes a real transform that can be used for various image applications such as compression and edge detection. The transform is based on the symmetric extension of a two dimensional block of data and is similar to the DCT. This symmetric extension is shown to be effective for image compression and for detecting transitions in images. Future work on this subject is also discussed.
