ITERATIVE METHOD OF MOTION ESTIMATION BETWEEN A REFERENCE IMAGE AND A CURRENT IMAGE, AND DEVICE FOR IMPLEMENTING SAID METHOD

摘要

This iterative method of motion estimation consists in producing a fixed number of iterations, each iteration consisting in: sampling 8, 9 the two images with increasing resolution at each iteration; detecting characteristic samples in the reference image 11 '; estimating a local motion vector 14 'for each characteristic sample of the reference image, by initializing this estimate with a displacement vector deduced from an overall motion estimation, carried out during the iteration preceding the current iteration ; - Estimate the overall motion of the current image, by calculating the parameter values of a model 13 ', from the local motion vectors estimated during the last iteration.
