摘要：
A skew angle estimation approach based on the application of several time-frequency distributions of Cohen's class to the horizontal projection profile of the page is proposed for document processing. Our results prove that the Wigner-Ville is the best trade-off between accuracy and computational cost. (C) 1999 Elsevier Science B.V. All rights reserved.
