Video data defining a series of images is processed to define a first series of nodes in a first multidimensional space, each of the first series of nodes corresponding to an image of the series of images and its location in the first space defined in dependence on features of the respective image. A transformation function maps each of the nodes in the first multidimensional space onto a respective node in a second lower dimensionality multidimensional space while maintaining neighborhood relationships between nodes. A second series of nodes in the second multidimensional space is defined in accordance with the transformation function and a clustering analysis is performed in dependence on the nodes of the second multidimensional space.
