SCALE-SPACE ANALYSIS AND CORNER DETECTION ON DIGITAL CURVES USING A DISCRETE SCALE-SPACE KERNEL

摘要

This paper shows the application of the discrete scale-space kernel T(n;t) with continuous parameter to scale-space analysis of digital curves. The numerical problems that arise in the implementation are addressed in sequence and feasible solutions are proposed. The scale-space analysis is applied to corner detection. The corner detector is shown to operate successfully on noisy curves and at varying orientation. (C) 1997 Pattern Recognition Society. Published by Elsevier Science Ltd. [References: 20]
