In this paper we apply a novel non-uniform slant correction preprocessing technique to improve the recognition of offline handwritten text lines. The local slant correction is expressed as a global optimisation problem of the sequence of local slant angles. This is different to conventional slant removal techniques that rely on the average slant angle. Experiments based on a state-of-the-art handwritten...
In this paper we propose a novel approach to th tion of on-line handwritten text lines based on dynamic programming. We try to find the paths with the minimum cost between two consecutive text lines. Most steps of the proposed algorithm are based on off-line information. Hence the method can also be applied to off-line documents after a few minor changes. In our experiments we show that this dynamic...
A class of VLSI architectures is proposed for the computationally intensive task of polygon recognition in 3-D space. They make use of a set of local shape descriptors for polygons that are invariant under affine transformations. The recognition procedure is based on the matching of edge length ratios using a simplified version of the dynamic programming procedure commonly used for string matching...
