[EN] Alpha integration methods have been used for integrating stochastic
models and fusion in the context of detection (binary classification). Our work proposes separated score integration (SSI), a new method based on ...
This paper presents the next step in the evolution of multi-sensor wireless network systems in the early automatic detection of forest fires.This network allows remote monitoring of each of the locations as well as ...
[EN] In this paper we compare the performances of different variants of split-spectrum algorithms and
propose some new extensions based on the use of variable bandwidth filters equally spaced in
frequency and energy gain ...
[EN] Decision fusion consists in the combination of the outputs of multiple classifiers into a common decision that is more precise or stable. In most cases, however, only classical fusion techniques are considered. This ...
