Impossible differential (ID), zero-correlation (ZC), and integral attacks are a family of important on block ciphers. For example, the impossible attack was first cryptanalytic 7 rounds AES. Evaluating security ciphers against these is very but also challenging: Finding usually implies combinatorial optimization problem involving many parameters constraints that hard to solve using manual appro...

This study investigated human recognition of human-body postures. We used computer graphics to make natural and impossible (unnatural) poses of three-dimensional human-body models, and made two-dimensional images of them from different viewpoints to test recognition performance in a serial matching task. We found that the recognition performance was better for the natural poses than the impossi...

The study of sign languages provides a wide field of applications for computer vision systems, but the analysis of such gestures often leads to complex 3D reconstructions or to ambiguities. In this paper, we describe the architecture of an image analysis system that performs sign language analysis by using a prediction/verification approach. The system integrates a model of the sign language’s ...
