Abstract: This invention is related to a multi-scale image processing algorithm for enhancing contrast to noise ratio in an electronic representation of an image represented by a) decomposing said digital image into a set of detail images at multiple resolution levels and a residual image at a resolution level lower than said multiple resolution levels, b) processing said detail images, c) computing a processed image by applying a reconstruction algorithm to the residual image and the processed detail images, said reconstruction algorithm being such that if it were applied to the residual image and the detail images without processing, then said digital image or a close approximation thereof would be obtained. The processing comprises the steps of: d) calculating a local variance value for at least one detail image pixel within a neighbourhood of said detail image pixel; e) enhancing or suppressing at least one detail image pixel as a function of said local variance value and said detail image pixel value.

Abstract: This invention is related to a supervision system that monitors automated movements performed by components of an medical imaging modality, in order to ensure that the moving components behave as expected, while identifying at the same time potential conflicts with (alien) objects or persons in the medical scene. The invention is based on the analysis of differences between measured distance data obtained by a detector that is mounted on the medical imaging modality, and a calculated virtual model of the geometric state of the modality components in the medical scene.
Abstract: A method is provided for manufacturing a paper layer having a printed pattern for use in panels that at least include a substrate and a top layer. The top layer includes the paper layer. The method may involve providing the paper layer with an inkjet receiver coating by transporting the paper layer relative to a coater in a coating direction. The coated paper layer may be provided with at least a portion of the printed pattern using a digital inkjet printer that includes a housing containing print heads. Providing the printed pattern may involve using water based pigment containing inks. The printed pattern may include a wood motif having wood nerves extending generally in a nerve direction substantially corresponding to the coating direction. Providing the printed pattern may involve a relative motion between the digital inkjet printer and the paper layer during a printing operation in a printing direction substantially corresponding or substantially opposite to the coating direction.
