Image segmentation has attracted the attention of researchers for many decades. Different approaches have been developed in order to find out the solution in many different segmentation situations. In this paper a novel method for rock fracture image using improved pulse coupled neural networks (PCNN) is presented. We apply progressive scan and region marked method to detect accurate edges of rock...
This paper proposes a rock fracture image segmentation algorithm based on fractional differential theory. By iteratively convoluted with the new covering templates, the high frequency signals on a rock fracture image can be more effectively extracted than the Tiansi module which has been applied in image processing applications. This study is very meaningful for expanding the application areas of...
A new fingerprint matching algorithm using the elaborate combination of minutiae and curvature maps from fingerprint images is proposed in this paper. First of all, we propose a simple method for curvature calculation based on fingerprint orientation fields from fingerprint images. Secondly, a curvature-based minutia specifier, which appears to be a circular pattern, is introduced by taking sampling...
