Abstract: A method of printing a digital image includes printing authentication marks by applying an amplitude modulated raster print in a detection zone to an object, the printed area of the detection zone consisting of asymmetric raster dots, wherein at least two mutually non-parallel finder edges are printed from at least one finder zone to determine the position, boundary and orientation of the detection zone. A method of authenticating such a print includes capturing an image of the printed article; detecting the at least two finder edges to determine the detection zone from the image with halftone dot accuracy, comparing the captured print image of the detection zone with the resulting print images, and deciding on the basis of the comparison whether there is an original print on the article.

Abstract: A computer implemented method of skin identification having scales, especially reptile skin identification, includes the steps of acquiring at least one image of a skin portion to be identified, detecting of features corresponding to borders of scales in the image, building a graph of the repetitive pattern scales positions of detected scales, determining the outline of the detected scales and representing the detected scales based on their outline, and determining recognition features data of detected scales for traceable identification of the skin comprising scales. The detection of scales is based on scan lines.

Abstract: Current invention corresponds to a mobility vehicle that draws its properties from a special kind of a track that can change its rigidity. The track can become rigid on its lower part corresponding to a wheel shape with large diameter or become totally flexible as usual track on upper side for practical use. When rigid, the track correspond to circular wheel and thus plays a role of a wheel in contact with the ground. The upper part of the track remains flexible and allows to use space above a the track for practical reasons. More particularly, the invention relates to a mobile system including variable flexibility track and at least two rollers around which the variable flexibility track is wrapped, wherein the rollers are adapted to change the rigidity and the curvature of the track to adapt its shape to different functionalities as being a wheel or having a part of circular wheel with different curvature or being foldable.

Abstract: There is described an imaging device for capturing images of at least portions of moving objects. The system comprises a stationary camera lens configured for reproducing an image of at least a portion of each moving object in an imaging plane when said object moves across a capturing region. The device further comprises at least one image sensor located in the imaging plane for receiving the reproduced image of the at least a portion of the corresponding moving object and converting said image into electronic signals. The at least one image sensor is mounted on a sensor support adapted to be actuated in a manner that the at least one image sensor is moved in the imaging plane relative to the stationary camera lens, and in a manner that the motion of said at least one image sensor is synchronized with the motion of the moving object to be captured.
