Semi-quantitative system identification

Semi-quantitative system identification

System identification takes a space of possible models and a stream of observational data of a physical system, and attempts to identify the element of the model space that best describes the observed system. In traditional approaches, the model space is specified by a parameterized differential equation, and identification selects numerical parameter values so that simulation of the model best...

A quantitative semi-fragile JPEG2000 image authentication system

In this article, we propose a novel integrated approach to quantitative semi-fragile authentication of JPEG2000 images under a generic framework which combines ECC and PKI infrastructures. Firstly acceptable manipulations (e.g., re-encoding) which should pass authentication are defined based on considerations of some target applications. We propose a unique concept of lowest authenticable bit r...
