Uppaal is a new tool suit for automatic veri cation of networks of timed automata. In this paper we describe the diagnostic model-checking feature of Uppaal and illustrates its use...
We have created a math learning environment with game-like elements such as narrative, visual feedback, personalization, collection, etc. We made a study with four different versio...
This paper proposes a self-authentication scheme for color images, using a fragile data hiding method based on the Discrete Pascal Transform (DPT). The main contribution of this wo...
Abstract—Transmission of digital contents in unavoidable noiseprone environments demands sophisticated error detection and concealment techniques to restore the perceptual qualit...
We introduce a regularized kernel-based rule for unsupervised change detection based on a simpler version of the recently proposed kernel Fisher discriminant ratio. Compared to ot...
