PCT No. PCT/FR94/00057 Sec. 371 Date Jul. 19, 1995 Sec. 102(e) Date Jul. 19, 1995 PCT Filed Jan. 18, 1994 PCT Pub. No. WO94/17485 PCT Pub. Date Aug. 4, 1994A process for estimating disparity between images of a stereoscopic image by carrying out a hierarchical decomposition of each monoscopic image (Ir(t), Il(t)), by levels of resolution in order to build at least three pyramids of images of increasing resolution including one low-frequency image pyramid and two high-frequency image pyramids in the horizontal and vertical directions of the images. Subsequently a disparity D is estimated at the coarsest level of resolution and the estimate is refined in each level as the resolution increases.
