The invention relates to a medical image processing system comprising means for identifying a boundary of the object, and reference points of said object boundary within an observation window; and for decomposing said object boundary into boundary unit elements, centred at the reference points, means for coding each reference point including spatial information and intensity information relating to said reference point and the corresponding unit element; computing transform coefficients from said coding data. A finite number of said coefficients is used for representing said object boundary by a polynomial transform function. This system has means for comparing, matching, correlating, smoothing corresponding boundary portions of the object in different images, only by performing operations on the transform coefficients. These operations yield rotation, translation, scale change transform coefficients. |
