Abstract

The need to compress a digital image is a growing concern due to the ever-increasing resolution at which these pictures are recorded. This fact, combined with pixel depth, creates images that require more storage space. NASA has many projects that currently take images at high quality of the earth or various objects in space. These high-resolution images take up a large amount of storage space when stored in bmp, TIFF, or any uncompressed format. A newer format, JPEG-LS, has an improved compression ratio, improved encoding and decoding time, as well as retaining all of the original quality of the uncompressed image. The goal of this project is to implement the JPEG-LS algorithm through a hardware description language (HDL) in response to NASA's need to compress images. See Professor Looft or Bitar for additional materials.
