Abstract:
For each pixel of interest in a local region of an input image, an edge intensity in each of a plurality of predetermined directions is calculated. All directions in which the edge intensities are larger than an average value of the edge intensities are selected. For all pixels of interest in the local region, the edge intensities calculated for each of the selected directions are accumulated and output as an edge feature amount.
