1. A method performed by a computerized user device for selecting pictures from a sequence of pictures of an object in motion, comprising:
determining, for each picture in the sequence of pictures, a value of a motion feature of the object,
analyzing the values of the motion feature of the object by calculating inflection points in a curve of the values of the motion feature of the pictures in the sequence;
identifying, based on the inflection points in the curve, a first subset of pictures from the pictures in the sequence, wherein the first subset of pictures comprises pictures corresponding to the inflection points;
selecting, based on a second selection criterion, a second subset of pictures from the first subset of pictures; and
displaying the pictures in the second subset to a user for further selection.
