摘要:
AbstractImage digitizers, particularly video frame grabbers, are subject to the phenomenon of ‘jitter’. This is due to timing instabilities, and it manifests itself in a slight shifting of rows or columns of image data relative to neighbouring rows or columns. This can degrade displayed image quality and reduce the accuracy of measurements extracted from the objects within the image. This paper illustrates a method for quantifying the amount of jitter present in a digitized im
