Patent ID: 8374492

Claim:
A method for determining the salience map of an audio video document comprising: calculating a salience map in relation to the video part of said document, determining at least one audio descriptor representing said document, weighting the video salience map as a function of the variation of said audio descriptor, wherein when the sound level of each audio channel and the overall sound level are used as an audio descriptor, the gain of each audio channel is calculated as a function of the sound level and of the sound level of all the channels, and wherein a weighting window is determined for each pixel having a visual salience greater than a predetermined level, referred to as a visually salient pixel, the spatial position of the position of said visually salient pixel is determined in the picture, a weighting function of each channel is calculated for each visually salient pixel as a function of the gain of each audio channel and of the spatial position of the pixel within the picture.
