求高手翻译一段话哈
Images may be sampled at intervals on a fixed grid of points. While tesselations
other than the obvious one have certain advantages , for convenience we
will assume that the image is sampled on a square grid at regular intervals. Let
the measured brightness be Eij.k at the intersection of the ith row and jth
column in the kth image frame. Ideally, each measurement should be an
average over the area of a picture cell and over the length of the time interval.
In the experiments cited here we have taken samples at discrete points in space
and time instead.
In addition to being quantized in space and time, the measurements will in
practice be quantized in brightness as well. Further, noise will be apparent in
measurements obtained in any real system.
