What is JPEG2000

ECE533 Project Proposal

Background information

JPEG2000 is a new image-encoding standard that provides a feature set vital to many high end and emerging imaging applications. JPEG2000 provides high compression with image quality superior to all existing standard encoding techniques. This high compression and quality performance is due to the adaptation of wavelet transforms. Wavelet transforms are mathematical formulas that represent complex structures in the image, thereby compressing an extremely large amount of image data into a relatively small amount of compressed data. This compression technique allows applications to save compressed images with higher compression ratios and better image quality as compared to any other software currently in production.

JPEG2000 is a wavelet-based compression stored in a hierarchical format which contains several stored resolutions of the image in the same file without duplication. For that reason, a JPEG2000 compressed image can then be sent to a device in the resolution that best fits without additional storage overhead. LEAD Technologies has used its more than ten years in the imaging and compression developer toolkit marketplace to formulate a JPEG2000 product that offers developers the best JPEG2000 implementation available.

Approach

In this project, I will explore the features and characteristics of JPEG2000 and make comparisons between JPEG2000 and JPEG technology in several attributes. Also using Kakadu software to implement JPEG2000 standard and will demonstrate the basic features of JPEG2000.

l  Compare the basic aspects of JPEG2000 and JPEG image

l  Implement JPEG2000 image with Kakadu software

l  Performance comparison of JPEG2000 and JPEG image

Ø  Color images, Gray images, and Cartoon images

Ø  Compare the pixel size, Compression ratio, file size and Rate-distortion
