A new oil spill detection algorithm based on Dempster-Shafer evidence theory

چکیده
Features of oil spills and look-alikes in polarimetric synthetic aperture radar (SAR) images always play an important role spill detection. Many detection algorithms have been implemented based on these features. Although environmental factors such as wind speed are to distinguish look-alikes, some do not consider the factors. To more accurately image features, a new algorithm Dempster-Shafer evidence theory was proposed. The process taking account modeled using subjective Bayesian model. Faster-region convolutional neural networks (RCNN) model used for convolution results two models were fused at decision level theory. establishment test proposed completed our look-alike sample database that contains 1 798 samples information records related samples. analysis evaluation shows good ability detect higher rate, with identification rate greater than 75% false alarm lower 19% from experiments. A total 12 SAR collected validation algorithm. result has performance detecting overall 70%.

A NEW FUZZY MORPHOLOGY APPROACH BASED ON THE FUZZY-VALUED GENERALIZED DEMPSTER-SHAFER THEORY
In this paper, a new Fuzzy Morphology (FM) based on the GeneralizedDempster-Shafer Theory (GDST) is proposed. At first, in order to clarify the similarity ofdefinitions between Mathematical Morphology (MM) and Dempster-Shafer Theory (DST),dilation and erosion morphological operations are studied from a different viewpoint. Then,based on this similarity, a FM based on the GDST is proposed. Unlik...
متن کاملA Sensor-Based Scheme for Activity Recognition in Smart Homes using Dempster-Shafer Theory of Evidence
This paper proposes a scheme for activity recognition in sensor based smart homes using Dempster-Shafer theory of evidence. In this work, opinion owners and their belief masses are constructed from sensors and employed in a single-layered inference architecture. The belief masses are calculated using beta probability distribution function. The frames of opinion owners are derived automatically ...
متن کاملA Generalized Dempster-Shafer Evidence Theory
Dempster–Shafer evidence theory has been widely used in various fields of applications. Besides, it has been proven that the quantum theory has powerful capabilities of solving the decision making problems. However, due to the inconsistency of the expression, the classical Dempster–Shafer evidence theory modelled by real numbers can not be integrated directly with the quantum theory modelled by...
متن کامل13 The Dempster - Shafer Theory of Evidence
The drawbacks of pure probabilistic methods and of the certainty factor model have led us in recent years to consider alternate approaches. Particularly appealing is the mathematical theory of evidence developed by Arthur Dempster. We are convinced it merits careful study and interpretation in the context of expert systems. This theory was first set forth by Dempster in the 1960s and subsequent...
متن کاملMulti-View Forest: A New Ensemble Method based on Dempster-Shafer Evidence Theory
This paper proposes a new ensemble method that constructs an ensemble of tree-structured classifiers using multi-view learning. We are motivated by the fact that an ensemble can outperform its members providing that these classifiers are diverse and accurate. In order to construct diverse individual classifiers, we assume that the object to be classified is described by multiple feature sets (v...
