This paper presents a new method of anisotropy inspection and quantification in digital images. It allows to detect the measure the occurrence of each directions of an image. The human visual system is usually very powerful for anisotropy detection, because it performs this analysis at different levels. Local information (from details) and more global information (from spatial distribution of patterns) are simultaneously present for the treatment. We show thwt our methods of directions analysis. Moreover, our method directly processes grey level images, uses the inner part of the patterns instead of thier contours and is able to inspect all the directions of a picture. These specifications overcome most of the limitations of usual methods.
