Kaugseire mõjul nimetatakse siluvat filtrit madalpääsfiltriks (ingl low pass filter) ja erinevusi esile tõstvat – kõrgpääsfiltriks (ingl high pass ~). See on siiski vaid analoogia, mitte täpne vastavus, sest kaugseires on teised eesmärgid [...]

Ruumilisi filtreid tuleks eristada signaalitöötluses kasutatavatest sagedusfiltritest.
Low-pass filters are designed to emphasize low frequency features (large-area changes in brightness) and deemphasize the high frequency components of an image (local detail).
A low pass filter is the basis for most smoothing methods. An image is smoothed by decreasing the disparity between pixel values by averaging nearby pixels.
