Two-dimensional channel representation for multiple velocities
2003 (English)In: Proceedings of the 13th Scandinavian Conference of Image Analysis, SCIA 2003 / [ed] Josef Bigun and Tomas Gustavsson, Berlin, Heidelberg: SpringerLink , 2003, Vol. 2749, 356-362 p.Conference paper (Refereed)
We present a two-dimensional information representation, where small but overlapping Gaussian kernels are used to encode the data in a matrix. Apart from points we apply this to constraints that restrict the solution to a linear subspace. A localised decoding scheme accurately extracts multiple solutions together with an estimate of the covariances. We employ the method in optical flow computations to determine multiple velocities occurring at motion discontinuities.
