Method of analyzing an image composed of a matrix of pixels, each pixel being defined by at least one parameter value arranged in a parameter matrix (Y). The method comprises the steps of performing a differentiation operation on the parameter matrix (Y) resulting in a plurality of differentiation entries (D) arranged in a matrix. Sets of neighboring differentiation entries having nearly the same differentiation entry are determined. A path length is determined for the pixels in each set, indicating a number of entries in that set. Based on the path length and differentiation entry, a pixel is classified as natural or synthetic image content. |
