abstract = {The invention relates to a method of determining motion-related
features (Fm) pertaining to the motion of an object (1), which
method comprises obtaining a sequence of images (f1, f2,...,
fn) of the object (1), processing at least parts of the images
(f1, f2,..., fn) to extract a number of first-order features
from the images (f1, f2,..., fn), computing a number of
statistical values pertaining to the first-order features,
combining the statistical values into a number of histograms
(HLC, HG), and determining the motion- related features (Fm)
for the object (1) based on the histograms (HLC, HG).
Furthermore, the invention relates to a method for performing
motion classification for the motion of an object (1) captured
in a sequence of images (f1, f2,..., fn).; Such a motion
classification method comprises determining motion-related
features (Fm) for the images (f1, f2,..., fn) using the
described method of determining motion-related features (Fm),
and using the motion-related features (Fm) to classify the
motion of the object (1). The invention also relates to a
system (3) for determining motion-related features (Fm)
pertaining to an object (1) in an image (f1), and to a system
(4) for performing motion classification for the motion of an
object ( 1 ).}
