APPENDIX

Appendix A

The Declaration at the start of the Thesis, Page i, with its assertions, is no longer in force; these appendices include also non-original work, not distinguished by quotation marks.

Appendix A contains colour prints of several images printed in grayscale within the thesis.

An introduction to wavelet tests, illustrated in chapters 4 and 5, is shown in appendix B, where general information about wavelet coefficients decomposition is given; we have also given a detailed explanation of different Orthogonal and Biorthogonal wavelet families, quadrature mirror filters, especially Daubechies, Coiflet, Symlet and Bio CDF, along with some properties, rules and criteria.

Seven different wavelet based image coding algorithms, such as EZW, SPIHT and SFQ, developed during the 1993-98 period, are briefly explained in appendix C, highlighting the different coding methods used on the wavelet coefficient matrix. The comparative results on image quality, presented at the end of this appendix, show us how the wavelet techniques are of interest in achieving high quality in the reconstructed images at low bit rate.

Appendix D gives a brief, but complete and exhaustive explanation of JPEG 2000, a new image coding standard, developed by the JPEG group of experts, underlining how much this standard supersedes the other old and recent standards, in image quality, compression performance and functionality introduced and achievable.
