+
+    many more algorithms to come!
+    see what is in stock: http://www.cosy.sbg.ac.at/~pmeerw/Watermarking
+
+  and utility programs
+
+    cmp_pgm     - compute difference image, PSNR, ...
+    cmp_dct     - compute full-frame DCT domain difference image
+    cmp_dct8x8  - compute 8x8 block-based DCT difference image
+    cmp_dwt     - compute DWT domain difference image
+
+
+
+Contact: Comments are welcome!
+
+More algorithms will be added over time, I have implemented about 13
+watermarking algorithms in the spatial-, DCT-, and wavelet domain so far.
+
+Please report what problems you have, suggestions, ...
