Hi,

I am trying to detect moving white LEDs (non-blinking, always ON) but am having some difficulties when it comes to distinguishing the LEDs from a white object of similar size.

My current thresholding method: I am currently using simple HSV based thresholding followed by erosion/dilation to detect the LEDs and then fit a contour + bounding rectangle around it.

My question: Is there some colour space (something like LAB perhaps as seen in this tutorial ?) that allows one to distinguish between white coloured and luminous objects ?

I am trying to detect moving white LEDs (non-blinking, always ON) but am having some difficulties when it comes to distinguishing the LEDs from a white object of similar size.size. The issue is that some of the LEDs appear smaller than the other's (due to varying distances from the camera) and hence making it hard to distinguish them from random white specks.

I did attempt to use sparse optical flow but the issue is with drone's jerky movement, the optical flow tracking loses the points easily.
