JPEG 2000 ENCODER IMPLEMENTATION USING VHDL

Abstract

The new still compression image standard, JPEG2000, has emerged with a number of significant features that would allow it to be used efficiently over a wide variety of images. The scalability of the new standard is intended to allow trading off between compression rates and quality of images. Due to multi-resolution nature of wavelet transforms, they have been adopted by the JPEG2000 standard as the transform of choice. In this Dissertation, an implementation for a reconfigurable fully scalable Integer Wavelet Transform (IWT) unit that satisfies the specifications of the JPEG2000 standard has been presented. The implementation is based on the lifting scheme, which is the most computation efficient implementation of the discrete wavelet transform. This project aims to provide modules written in the Very High Speed Integrated Circuit Hardware Description Language (VHDL) that can be used to accelerate an existing software implementation of JPEG2000. iv
