[en] For the broadcast of live football games, a lot of people are required: the director chooses at any time the most interesting camera to show on TV while the so-called loggers encode the statistics of the match. More and more, we try to help those people by automating their tasks. To do so, artificial intelligence methods must be developed for computers to understand what happens on the pitch. In order to achieve this goal, many subproblems must be solved separately. Automatic identification of players is one of them. This master thesis tries to handle this specific problem by focusing on the players numbers. The whole work is separated into 3 main parts: player detection, digit detection and digit recognition. Those different tasks are tackled with the help of computer vision and deep learning techniques. In particular, a segmentation semantic method is implemented. This allows us to know whether a pixel in the image belongs to a player or a digit with an accuracy higher than 98%. Digit recognition also obtains very promising performances. On the whole, this master thesis offers an array of techniques for each individual task. With more training data, those techniques would give robust models that could be applied to any football game.
