摘要： Image processing system for generating a multidimensional adaptive oriented filter to process image data in a number d of dimensions, comprising product means for producing weighted scalar coefficients [W1(r), . . . Wi(r), . . . Wd(r)] of a number d of vectors of an oriented basis of vectors by a number n of local vectors related to each point; combining means (Π) for producing a set of one-scalar weight coefficients [W(r)] from the combination of the weighted scalar products; and filtering means (g) for producing filtered image data [g(x)] from the combination of the image data [I(x)] with the one-scalar weight coefficients [W(r)]. The system further comprises a direction estimator (10) for providing, at each image point, an oriented orthogonal basis of a number d of vectors (e1, . . . ei, . . . ed); a site generator (20) for providing n site vectors of a local vector support; and product means for computing d scalar products of vectors of the orthogonal basis by each of the n site vectors. This system may also comprise means for providing weighting means for the scalar products through scalar functions. The filtering means may comprise a weighted normalized sum of the image data by the one-scalar weight coefficients [W(r)].

摘要： An image processing method and an X-ray apparatus in which a thread-like structure represented on the background in a noisy digital original image is extracted. Original image data is acquired and reduced using a transformation operation so as to provide a reduced image. The most probable locations of guide-wire points in the reduced image are selected by selecting at each point the direction of the guide-wire which provides the best match with one of several predetermined regularly oriented directions and by probing the contrast around and in the selected directions and then probing the contrast around selected locations in the original image corresponding to the selected location of points in the reduced image. Then, the points which satisfy a contrast condition are extracted and the points which also satisfy a connectivity criterion in the reduced image are connected and these points are extracted as guide-wire points of the original image.

摘要： Method and device for binary segmentation of a digital image with a threshold obtained using a histogram to obtain a binary segmented digital image. The digital image is thresholded a number of grey levels, and the number of objects which appear when the digital image is thresholded at each of the grey levels is counted. A histogram of the number of objects per grey level is constructed, and a segmentation threshold is determined automatically on the basis of the histogram. The digital image is then thresholded at the segmentation threshold to obtain the binary segmented digital image.

摘要： A method and device for use in detecting moving targets in a scene represented by a sequence of mutually registered images R ( . . . , R.sub.n-1, R.sub.n, R.sub.n+1, . . . ) over time wherein differential images D ( . . . , D.sub.n-1, D.sub.n, D.sub.n+1, . . . ) are derived from succeeding images R, and spatially low pass filtered to obtain a sequence of filtered differential images F ( . . . , F.sub.n-1, F.sub.n, D.sub.n+1, . . . ). For each pixel of a plurality of pixels (i,j) and for each of a plurality of directions (d.sub.x,d.sub.y), a sum of intensities is formed from a number of successive frames of the sequence of filtered differential images F.sub.n-m (m=0,1 . . . M) at pixel locations (i+md.sub.x,j+md.sub.y) located, as the image is further back in time, along the direction progressively outwards from the pixel. For each pixel of the plurality of pixels, an intensities is determined which represents for the maximum size among the sums among the plurality of directions, the intensity for each pixel collectively forming an image G.sub.n.

摘要： A method and an image processing system for the evaluation of projection images generated by an X-ray imaging system, wherein the images may show different instruments of a given set of interventional instruments like catheters or guide wires. The instruments are equipped with markers such that their configuration is characteristic of the corresponding instrument. Preferably three markers are arranged on a straight line, the ratio of the distances between them being characteristic for the corresponding instrument. The image processing system may then identify the instruments present in a given projection and provide functionalities for a user that correspond to said instruments. Moreover, the system may be used to locate an instrument of interest in a projection image if the marker configuration of that instrument is known a priori.
