View Full Version : image always moving
September 20, 2004, 15:16:39
I am wondering if the image my cammera gets is always supposed to be changing when objects are not even moving? my angle, perimeter, and area are constanly changing even when I put numerous types of filters in. The cammera is a dfk 21f04. I can not even really use the HU invariants at this point because the shape of the image changes to much.

it seems the best way to smooth that out is with the mv smooth sequence but then 2-3 frames have the exact same value for colors? wouldn't this cut my frames down from 1/2, 1/3??? Unless some one has a better solution.

The camera noise is the reason for the changing objects. The only thing you can do is actually to smooth the image by frame averaging (MV Smooth Sequence), spatial filtering (MV Linear Filter or MV Convolution) or median filtering (MV Nonlinear Filter).
MV Smooth Sequence does not decrease your frame rate, it jst averages the frames and therefore the information of all input frames is included in the resulting output frames.
