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 ).
