Can`t capture small objects #46

Closed tarasevich-dmitry closed 5 years ago

tarasevich-dmitry commented 5 years ago

Hello, I can't capture some small objects with bounding box, it's just impossible to set it. However when I try a bit bigger box (that is out of size of my object) it works, looks like it is some limit. See screens attached. Any suggestions?

OpenCV version '3.4.5'

Hi @tarasevich-dmitry , I think you can adjust the minimum threshold of bounding box. screenshot from 2019-02-15 20-07-14

@vuthede Thanks for advice! But as it was mentioned in comment, is it some errors may occur with small size boxes?

vuthede commented 5 years ago

@tarasevich-dmitry No problem! I think there would not be an actual error when the bbox was small. I guess the author just want to avoid some cases. For example, when we unexpectedly create some very small bbox due to unexpected mouse-click event and we can not see it because it is very small. Or in the case that the first left-mouse click and the second one are the same point

Ok, thanks ones again! Guess I can close this issue now

Hello, yeah @vuthede is right, I added to avoid creating bounding boxes by mistake, since we don't have a "go back" or ctrl + z feature yet. I will reduce the threshold from 20 to 10!
