I would like to determine the shortest distance from one point to its closets neighboring point to compute for the insect distribution.
Attached is an example of the images I'll be working on. This is an image of a leaf infested with a kind of insect (black tear drop-shaped object). I can manually place "points" to locate these insects in the picture. I would like to know how to get the shortest distance between any insect and its closest neighboring insect.
1. How do I place this "points"?
2. How do I get the measurements (distance to the closest neighboring insect)?
It is basically finding minimum distance of two set of points (any two segments). Check this: https://stackoverflow.com/questions/15093953/euclidean-distance-between-two-set-of-3d-points
manually doing will be tedious job moreover one more thing needs to be consider is the time frame (age) of insect the minimum distance may vary according to life stages they are in u can use any software which clearly identify insects thereafter cluster analysis can be done.
Trung Huy Duoy, thank you for your suggestion, however I am not familiar with coding and macros.
Ji-Youn Arns, I have not used Drishti before that's why I asking specifically about ImageJ. I have found the Drishti software, but I am still not sure on how to use it for my problem. It seems that Drishti is good in 3D object measurements, editing, and etc, but I have not seen any reference yet on how I can use it for my problem.
If you have any document that may help me understand Drishti a little bit more for me to be able to use it in my problem, that would be very much appreciated.
Himmat Sing, thank you for pointing out your concern about the life stage of the insect which may affect distribution.
The reason why each insect would have to be "tagged" by manually placing "points" is specifically because of you concern with the age of the insect. That's why, even if it will be tedious, I should "tag" each one according to my knowledge of the life stage of the insect in a particular picture.
Moreover, the insect in this study is remains attached (not moving) when they reached maturity.
