Document Type and Number:
Japanese Patent JP2006516908
Kind Code:
A
Abstract:
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 (Pi) 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)].
