Classification: CPC G | IPC G

Claim 13:
14. A non-transitory computer-readable medium having an image-processing program stored therein, the program causing a computer to execute functions of:
setting a plurality of discrete measurement regions in a standard image and a reference image selected from a plurality of images acquired in a time series manner and of calculating motion vectors in the respective measurement regions;
setting a region of interest in the standard image;
selecting, from the plurality of calculated motion vectors, the motion vectors in the set region of interest;
estimating a homographic-transformation matrix that represents a motion in the region of interest by using the selected motion vectors;
evaluating the homographic-transformation matrix on the basis of the estimated homographic-transformation matrix and the plurality of calculated motion vectors; and
re-setting, on the basis of the evaluation result, a new region of interest a size of which is increased as compared with that of the set region of interest.
