[imgSeek-devel] Small patch to increase score

[Daniel F. <gu...@ac...>]

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%
