Abstract: A method for generating an output image by reducing the size of an input image by determining for a pixel location (i,j) in the output image a corresponding areaxy in the input image, fetching the input image areaxy pixel values, calculating an output pixel value Dij for the pixel location (i,j) using a size reducing algorithm, inserting Dij in the output image and repeating the previous steps for each pixel location (i,j) in the output image. The value Di,j is obtained by adding to the lower resolution background representation A of the input image area pixel values with a value obtained by amplifying MED, representing the pixel value in the input image area that most deviates from said lower resolution background representation A, by means of a significance factor SF.
Abstract: For each of a number of landmarks in an image an initial position of the landmark is defined. Next a neighborhood around the initial position, comprising a number of candidate locations of the landmark is sampled and a cost is associated with each of the candidate locations. A cost function expressing a weighted sum of overall gray level cost and overall shape cost for all candidate locations is optimized. A segmented anatomic entity is defined as a path through a selected combination of candidate locations for which combination the cost function is optimized.

Abstract: A printing method wherein a lay out composition for a print sheet is defined as a hierarchical set of cells, independent of characteristics of a printing device. A printing model is generated for at least one image to be printed and/or associated annotation data by means of this lay out composition and links to data files. The printing model is converted into a bit map representation taking into account the printing characteristics of the printing device.
Abstract: A method of creating a gradation curve for gradation processing of a medical image represented by a digital signal representation to generate a gradation processed image wherein the shape of the gradation curve and signal range for which the gradation curve is defined are deduced from the digital signal representation and wherein the gradation processed image has a fixed density and fixed contrast value in a diagnostically most relevant area.
Abstract: A method and system for reproducing an image on a carrier, the method includes: generating a conjoined first and second sub-image, each representative for a portion of the image; defining an overlap region where both sub-images give a contribution to the internal optical density of the carrier; dividing the overlap region in a partition of microdots; establishing for each sub-image a peripheral edge in the overlap region; increasing the contribution by the first sub-image from the peripheral edge of the first sub-image to the peripheral edge of the second sub-image; and assigning to at least one microdot an intermediate microscopic density different from a minimum or maximum microscopic density of microdots; wherein the contribution increases the microscopic density of the microdots by density steps smaller than half the difference between the minimum and maximum microscopic densities of the microdots.
