Ground Truth bad labels

[iago-suarez]

I was trying to evaluate the Line segment descriptor published in OpenCV with this algorithm, but I've found that some of the files have incorrect matches.

I added a cv::imshow to the main.cpp in order to show the line matches, and I found that for the leuven images there are a lot of wrong matches in the Ground Truth:

Executing ResultEvaluation .../LineMatchingBenchmark/benchmark/leuven/ img1.ppm img6.ppm lsd1.txt lsd6.txt LSD .../LineMatchingBenchmark/benchmark/leuven/lsd_GroundTruthMatches.txt

The first match is wrong:

The second match is also wrong:

The fourth match is also wrong:

*NOTE: I've also changed the color of the good matches from blue to green to make them look better.

Thank you for pointing them out. We have double-check the labels recently. Please feel free to contact with us for other problems you find, which will definitively help us refine the benchmark. Thanks.
