Evaluation with Precision over 1 #2

Open Sefray opened 2 years ago

Sefray commented 2 years ago

Description

Using evaluation, output precision might be over 1.

How to reproduce

Truth file 20,10,20,50 30,10,30,50

Predicted line segment 25,17,25,52

True positive conditions

eval_param.thres_dist = 10;
eval_param.thres_ang = pi*5/180;
eval_param.thres_length_ratio = .75;

Output must be :

precision : 1.8857142857142857
recal : 0.825
iou : 0.9428571428571428
fscore : 1.1478260869565218

Cause

Multiple matching for Predicteds on Truths.

Hi, Sefray. Thanks for bringing up this issue. You are correct. I will come back with more detailed answers later. I need to spend some time remembering the code - it's been a long time since the release.
