JPEG2000 Hardware Implementation - Procedures and Issues
Author:
Abstract: Hardware implementation of JPEG 2000 compression/decompression standard, applicable to the realtime image sequences, is discussed in this article. The general system-level design along with its details are presented. In this work, for clarity and ease of understanding, implementation of lossless and lossy compressions are treated independently. Depending on the application, usually one implementation is preferred over the other and in general there is no need to include both methods on the same hardware platform. For multi-level decomposition, it is assumed that the LL component of the previous stage, i.e., scale-coefficient, is fed back to the same hardware for further decomposition. Lifting approach along with convolution method and polyphase decomposition for implementation of the forward and inverse discrete wavelet transform (DWT) are discussed.
