Following are the results of running ghash across a more extensive test sample.
Percentage of collisions across all attacks per resolution/fuzziness pair:
res=8 res=4 res=3
---------+------------------------------
fuzz=0 | 30.37 68.15 83.70
fuzz=5 | 30.37 72.22 81.85
fuzz=10 | 38.15 75.56 86.30
A total of 30 images under 9 attacks were examined.
These results were generated by index.js. Intermediate output has been truncated for brevity's sake.
