Recently, an efficient video coding method at low bit rate using Matching Pursuits (MP) has been proposed. The MP coding method represents a signal in an approximate form using a dictionary. Therefore, coding performance depends greatly on the dictionary. In this paper, we introduce a video coding method that employs motion compensation and MP using a dynamic learning dictionary. The dictionary of the proposed method is renewed at each frame by using encoded information. Simulation results show that the coding performance of MP can be improved by applying the dynamic learning dictionary.
