I have the following problem. I have 8-bit image. It represents photon counts, so each pixel is capable to register up to 255 photons. I need to introduce some random error – each photons trajectory is disturbed, so that finaly instead of e.g. (150, 100) it is regiesterd at (150+random1, 100+random2). Random1 and random2 both have Poisson distirbution and are small, ~2 pixels.
Notice, that is is not enough to displace each pixel in random direction, since each count from each pixel has to be displaced separately.
What is the easiest and fastest way to code it?
Best regards, Alex
