1. A method for the quantitative and visual analysis of motion in a time sequence of images comprising the steps of: a) determination of the motion vectors for each point in the image space between images of directly or not directly subsequent time steps (i.e., the transformation of the corresponding image space) preferably by means of rigid, affine and/or “elastic” (including local deformations) overlapping/registration of images of an image sequence and calculation of the transformation parameter comprising the following further method steps: a1) for the non-rigid registration, local transformation types are given stepwise from coarse to fine, first global and then increasingly more local; a2) for more then two time steps, in order to obtain the transformation for not directly subsequent timesteps, the transformation is not only calculated in pairs for subsequent image pairs, but also a correction-registration step is further added thereto; a3) from the transformation result directly the local, defined for each point in the image/time space, quantities velocity, acceleration, warp, tension, deviation from the finest registration (i.e., distance between the point transformed by the selected transformation type and by the most local fineness level), etc. as well as the global quantities warp energy for the entire motion as well as for each “principal warp” separately (Bookstein 1989), entropy, “directedness” of the motion and the transformation parameters for various fineness levels of the transformation; b) reconstruction of the space-time-structure within the image space and visualization thereof by means of b1) (optionally interactive) determination of a point (or a region; or according to a regular scheme selected point in the space or on the surface of a region) for a selectable moment, the automatic calculation of its (their) position for all other moments by means of the under a) calculated transformation (for not directly subsequent time steps) as well as the interpolated representation as 3D rendered (surface rendering) path (or “tube” for regions); and/or b2) a 3D rendered reference grid, deformed according to the transformation calculated in a), animated (interpolation of intermediate time steps) or not (animation also continuously over several time steps), the image space overlapped (inserted) or not; in an image record having several color channels, the reference grids corresponding to the various separately treated color channels can be represented in different color but simultaneously; and/or b3) color/pattern encoding (including gray value encoding) of quantities (quantities having vector values by means of absolute values), which are assigned to a point in the image/time space as described under a), particularly for (i) all points, lying within an interactively selectable level of the image space, (ii) interactively (or regularly) selected points or surface points of interactively selected regions/shapes/surfaces (iii) the points of the under b1) determined path (or tubes) of the time space; and/or b4) a motion corrected representation of the paths (or tubes), corrected by a rigid, affine or a selected level of the non-global transformation, or by means of a motion corrected playing of the original image sequence, particularly the color encoding can be back projected onto the original image or any other given moment.
