The idea of the invention is to produce an optical flow uniquely determining points of correspondence for points between original images on the surface of the original images. The flow is determined in such a way that all of the new images to be formed between the original images can be formed by means of the same optical flow. Each motion vector of the flow has a permitted area of movement defined by the motion vectors surrounding said motion vector, within the bounds of which its direction can move when the flow is formed. The area of movement is used as an additional constraint the satisfying of which will ensure the uniqueness of the flow. A unique flow is realized by adjusting the proportion of cross-correlation taking account of motion and of the smoothness criterion when the flow is formed, in such a way that in the vicinity of violation of the additional constraints, the proportion of cross-correlation taking account of motion is suppressed. This should preferably be done in such a way that the proportion of the cross-correlation is zeroed when the additional constraints are violated. |
