The present invention relates to a method of detection and recognition of logos in a video data stream comprising the steps of sampling (1) frames of said video data stream; segmenting (3) regular shapes such as, for example, circles, ellipses and rectangles; generating (4) a vector of feature parameters of an image contained in each of said shapes; and comparing said feature parameters with a database for determining (5) whether the images correspond to logos. The frames are captured preferably using a sampling frequency which is dynamically adapted to processing times, for the purpose of allowing the system to work in real time.
