Signature image recognition by shape context image matching

Adamski M., Saeed K.

Journal of Medical Informatics & Technologies

2007

Vol. 11

89--95

This paper presents experiments on recognition of signature images. In preprocessing stage a thinning algorithm is used followed by a sampling technique. Sampled points are used to calculate shape context histograms and based on their values corresponding pairs of points from reference and tested signature objects are selected. A distance measure based on shape contexts is used to classify analysed signatures.
