Algorithm for recognition of anisotropic images

Algorithm for recognition of anisotropic images is suggested. Essential property of such images is presence of two types of area: tracks of identifiable instruments named anisotropic and background as isotropic. For recognition of anisotropic images is necessary to estimate contour of instrument's blade, which made tracks. Tracks are linear traces. We use power spectrum properties of anisotropic images for image segmentation and for estimation of traces direction. After that we estimate contour of instrument's blade.
