Qualitative estimations of range and motion using spatio-temporal textural images

In this paper we model the problem of structure from motion as the range estimation with known motion. First, we approximate the motion within a reasonable time interval as a 3D translation and thus some image transformations are applied to convert an arbitrary motion to a 1D translation. Then we analyse the epipolar plane image in the Fourier domain to avoid the feature extraction and correspondence problems. Experimental results with real scene images have shown the efficiency and robustness of the approach.
