The sources of noise

Noise in images perturbs measurements and makes the lives of image analysis people interesting. There are many sources of noise, depending on the imaging modality: photon noise, thermal noise, electronic noise, quantization noise, etc. I have just found out about another source of noise: etheric entities. Apparently these etheric entities appear especially in “certain photos of human/reptilian hybrids such as Bush or Obama,” and are completely indistinguishable from other types of noise. I’m not looking forward to test my algorithms against this form of noise.
