摘要： The invention relates to a method for positional optimization in navigation, in particular neural navigation in surgery with an operation microscope and at least one optoelectronic image detector which may be connected to the microscope and also a computer system. The data obtained from the at least one image detector which lie in the microscope field-of-view for the operator, contain information on the position of an operation instrument, in particular the instrument tip. The actual position of the instrument in the x- and y-direction as well as in the z-direction of a three-dimensional coordinate system is continuously or intermittently determined from the relevant positional data. A separation determination is carried out for the positional determination in the z-direction by means of depth of focus evaluation and/or stereoscopic image analysis. The invention further relates to a navigation instrument, using marking, close to the instrument tip, lying within the field of view of the microscope during use thereof.

摘要： For time-sequential segment tracing, also of moving regions, a method of segmenting time-sequential images of a picture signal, in which, within an image, the image is split up into regions during its segmentation, and in which adjacent pixels having similar luminance and/or chrominance values are associated with a region is characterized in that it is attempted in time-sequential images to retrace regions of an image I.sub.n in a subsequent image I.sub.n+1 by performing a motion estimation of the regions of the image I.sub.n, in that the new position of the region in the image I.sub.n+1 is determined with reference to the motion vectors determined for each region by means of the motion estimation, in that subsequently the displaced regions are adapted to the image contents of the image I.sub.n+1, and in that pixels of the image I.sub.n+1 not covered by these adapted regions are added to one of these regions or to newly formed regions.

摘要： To achieve an enhanced data reduction, a method of fractal image coding, in which method an image to be encoded is divided into range blocks which do not overlap and jointly cover the image contents completely, in which domain blocks comprising areas of the image contents in their original form or in a transformed form are generated from the image contents, and all areas of the image contents are covered by at least one domain block, for each range block the domain block most similar to the range block being searched, and the addresses of the domain blocks found as the most similar and possibly the transform functions used for their generation being transmitted instead of the data of the range blocks, is characterized in that, in a sequence of images, the fractal image coding performed exclusively within the images is only performed with basic images comprised in the image sequence at selectable time intervals, in that, for intermediate images provided between the basic images, the same range and domain block division is used as for the basic images, and in that, individually for each range block in a search area, that domain block is searched in an intermediate image which was found as the most similar in the previous image for the range block of the same position, and in that, if said domain block is found in the search area, the displacement vectors of this block relative to the domain block found as the most similar in the previous image are transmitted instead of the address and possibly the transform function.
