82 many more algorithms to come!
83 see what is in stock: http://www.cosy.sbg.ac.at/~pmeerw/Watermarking
84
85 and utility programs
86
87 cmp_pgm - compute difference image, PSNR, ...
88 cmp_dct - compute full-frame DCT domain difference image
89 cmp_dct8x8 - compute 8x8 block-based DCT difference image
90 cmp_dwt - compute DWT domain difference image
91
92 What do I need?
93
94 Unix (Linux), a reasonable C compiler (GCC), and the netpbm library which you
95 can get at http://wuarchive.wustl.edu/graphics/graphics/packages/NetPBM/
96
97
98 Directions: How do I use the stuff?
99
100 look at the MAKEFILE...
101 each algorithms has at least 4 files: gen_algo_sig.c, wm_algo_e.c, wm_algo_d.c,
102 cmp_algo_sig.c where 'algo' is the name of the actual watermarking algorithm
103 (usually the principal author's name), where might also be some common files
104 for each algorithm, algo_common.{c|h}, and some support files for sorting,
105 the DCT, ...
106
107 just try
108
109 make
110 make test
111
112 next, try to run each program with the -h parameter to find out what options
113 are supported - the programs are pretty consistent and have reasonable
114 default settings
115
116 e.g.
117
118 wm_cox_e -h
119
120 The programs all support standard input and standard output, the only
121 supported image file format is PGM for grayscale images and PPM for color
122 images; most programs have only been tested with 512x512 images.
123 You can find the Lena image in PGM format in the images/ sub-directory.

142 More algorithms will be added over time, I have implemented about 13
143 watermarking algorithms in the spatial-, DCT-, and wavelet domain so far.
