Abstract:
A processor-implemented method of analyzing an information signal having a texture, the method comprising the steps of:extracting texture-related features from the information signal; and generating an output signal representative of at least one of a directionality, a symmetry and a, regularity of the texture, based on the extracted features, wherein the step of extracting texture-related features further includes the step of computing a feature vector as fT=[dx dy sx sy rx,m rx,s rx,f ry,m ry,s ry,f], where dx and dy represent measures of horizontal and vertical directionality, rx,m, rx,s and rx,f are regularity features along a horizontal axis, ry,m, ry,s and ry,f are regularity features along a vertical axis, and sx and sy are measures of symmetry along the horizontal and vertical axes.
