I guess you cant just substract the two images to remove the noise, because there is always some movement with the camera....it cant be steady.....so u end up making a mess instead...

My call would be use "inrange" function, if a pixel is fully bright, i.e. 255 or say above 200, leave it as it is otherwise just make it zero..... thus you end up with just the led part...background gone!!
