Storing biometric templates and/or encryption keys, as adopted in traditional biometrics-based authentication methods, has raised a matter of serious concern. To address such a concern, biometric key generation, which derives encryption keys directly from statistical features of biometric data, has emerged to be a promising approach. Existing methods of this approach, however, are generally unable...
Regional difference is the kernel guidance in the area of image segmentation. In this paper, we present a novel region-based active contour model that could be applied to detect the contour of both nucleolus and cell membrane from the background. Both local and global intensity information are used as the driving forces of the active contour model on the principle of maximum regional difference. The...
