In reply to your question about lossy compression techniques, I would
recommend the following recently published book:
``Digital Image Compression Techniques'' by M. Rabbani and P. W. Jones
(Tutorial Text Series, Vol. TT7, SPIE Press, Bellingham, WA, 1991).
As you can see, the book has been written as part of a tutorial series
put out by SPIE (Society of Photographic Instrumentation Engineers), so
it's a good text for those just getting involved in image compression
(i.e., there's a lot of description, with just enough theory to get the
point across). It's also a good reference for people who are already familiar
with compression since it includes more recent techniques such as vector
quantization and subband coding as well as many references for more
in-depth research.
There is also a discussion of image compression standards and a detailed
description of the JPEG baseline system. Actual compressed/decompressed
images are shown for JPEG and for the other techniques discussed in the book.
Besides lossy techniques, sections are included on lossless techniques
and information theory basics for image compression. The book is broken
down as follows:
Part 1: Background - Digital images and image compression.
Part 2: Information Theory Concepts - Source models and entropy, Variable-
length codes, Entropy estimation and lossless compression, Rate-
distortion theory and lossy compression.
Part 3: Lossless Compression Techniques - Bit plane encoding, Lossless
predictive coding, Lossy plus lossless residual encoding.
Part 4: Lossy Compression Techniques - Lossy predictive coding (DPCM),
Transform coding (includes JPEG baseline algorithm), Block truncation
coding, Vector quantization, Subband coding, Hierarchical coding,
Choosing a lossy compression technique.
Appendix: Compression of color images.
Disclaimer: I know the authors personally, but don't hold that against them.
