摘要： A computer-implemented method for detection of fiber pathways includes determining initial data as a subset of voxels that have been selected from a diffusion tensor image by applying a threshold to fractional anisotropy values, determining a cluster of points with highly collinear diffusion directions, and performing region growth to find suitable seed points in a plane that is normal to the cluster's mean direction, starting from the center of the cluster. The method further includes tracing pathways from the seed points, eliminating voxels of the subset from the initial data that are close to any of the pathways using a distance threshold, displaying a visualization of a selection of voxels used as seed points and of the pathways traced from the seed points.

摘要： A method of processing images in images comprising curvilinear structures comprises, in parallel, a step of filtering said images and a decision step intended to select the pixels of the images pertaining to a curvilinear structure, the method comprising, in parallel, a sub-step of estimating the direction of each image pixel, as well as a sub-step of analyzing the connectivity of neighboring pixels based on their directions at the end of the sub-step of estimating the direction of each image pixel, and a sub-step of selecting groups of pixels as a function of the result of the sub-step of analyzing the connectivity of neighboring pixels based on their directions, at the end of the step of filtering. Such a method allows selection of curvilinear structures which are fine structures such as a catheter in a medical image, or thicker structures such as a tree-like structure of blood vessels. This method may be used, for example, in medical scanning apparatus for detecting artery anomalies such as stenosis or a diffuse coronary disease.

摘要： The invention concerns a medical imaging station including segmentation means for segmenting at least one imaged object in an image having gray levels, by propagating an edge from at least one initial point positioned in the image on the imaged object. The speed of propagation of the edge depends on said gray levels at each point referred to as a current point and the segmentation means segmenting the image between the points over which the edge passes and the points over which the edge does not pass. According to the invention, the edge propagation means are coupled with means of automatically detecting an emergence of the propagation edge from the imaged object at a current point. Means of locally fixing the speed of propagation at zero at this current point are activated in the event of detection of an emergence of the propagation edge.

摘要： A method for contour stroke generation. First, edge pixels of an image are detected. The connected edge pixels are traced to generate non-branched edges. Each non-branched edge represents a list of connected edge pixels without branches. Thereafter, the non-branched edges are clustered. Then, the non-branched edges are transformed into curves, and the curves are drawn with a series of footprints to generate contour strokes of the image.

摘要： In a system for segmenting a pixel based image, pixels containing image boundaries are identified. The image boundaries are then fattened by repeatedly adding fattening rows of pixels to the pixels containing boundaries to separate the remaining pixels into separate segments. The separate segments are then grown back to their original size before the boundaries were fattened. This operation has the effect of linking the boundaries together to separate the image into segments and to extend incomplete boundaries into complete boundaries around segments in the image.
