Hi This is my fist post to the list so please be gentle ;) Anyway, I found out that if I compare two identical images with ImgSeek I get a really low score (~30%) The problem lies in imgdb.cpp where the reading of an image is done differently depending on whether the image should be added to the database or is read for comparison. The following patch fixes that problem: http://www.cs.umu.se/~fahlgren/public/imgseek/imgseek-0.8.5rc1.patch The patch is against 0.8.5-rc1 as the name indicates. Why the scores differs so greatly I don't know. Someone with more insight in haar transformations might perhaps enlighten me? With my test image the score changes from 26% to 92% Regards Daniel Fahlgren |
