Abstract: A device for reducing structural vibrations of aerofoils in an aircraft comprises, in the region of the aerfoil tips, at least one force generator (24a) acting substantially in the direction of movement of the vibrations.

Abstract: An automatic learning method for the automatic learning of the forms of appearance of objects in images in the form of object features (28) from training images (20) for using the learned object features (28) in an image processing system comprises determining a feature contribution (30) by a training image (20) to object features (28) by weighted summation of training image features by means of linear filter operations, applied to the feature image (24), by using a weight image (32) obtained at least from an annotation image (22) and a classification image (26). This allows faster learning processes and also the learning of a greater variance of forms of appearance of objects and backgrounds, which increases the robustness of the system in its application to untrained images.
