The optimization methods of a classical video encoder process the information to reduce it only as a signal point of view, and are therefore «low level». Although some works incorporating the HVS properties have been proposed to assess the quality, or to improve the coding, these methods have not been included in the standards. Researchs focus more on the improvment of new standards, such as H.264. However, the performances of the «high level» methods are encouraging. We therefore propose a method of pre-analysis of videos, that incorporates a visual attention model. This model aims at analyzing the video taking into account the high level information, in order to transmit to the encoder an optimal set of parameters, and to exploit efficien...
