Abstract:
1. A computer implementable method comprising: (a) generating at least one saliency map of a plurality of saliency maps, the at least one saliency map characterized by at least a number of pixels equal to a number of pixels within a source audiovisual content and each pixel within the at least one saliency map having a value associated with it which is determined in dependence upon determining at least a saliency for the corresponding pixel within the source audiovisual content; (b) generating at least one reduced saliency map of a plurality of reduced saliency maps, each reduced saliency map associated with a predetermined saliency map of the plurality of saliency maps and generated by applying at least one predetermined scaling factor X, where X>1 and is an integer, to the predetermined saliency map of the plurality of saliency maps thereby reducing at least a dimension of the predetermined saliency map of the plurality of saliency maps by the factor X; (c) applying a path determination process to the at least one reduced saliency map, the path determination process for identifying a sequence of pixels within the at least one reduced saliency map that meet a predetermined condition; and (d) modifying the source audiovisual content in dependence upon at least the sequence of pixels.
