Description: 一个基于图形的高效图像分割算法，包括论文及相应的源代码。-This paper addresses the problem of segmenting an image into regions. We define a predicate for
measuring the evidence for a boundary between two regions using a graph-based representation of the image. We
then develop an efficient segmentation algorithm based on this predicate, and show that although this algorithm
makes greedy decisions it produces segmentations that satisfy global properties. We apply the algorithm to image
segmentation using two different kinds of local neighborhoods in constructing the graph, and illustrate the results
with both real and synthetic images. The algorithm runs in time nearly linear in the number of graph edges and
is also fast in practice. An important characteristic of the method is its ability to preserve detail in low-variability
image regions while ignoring detail in high-variability regions

fuzzy membership function to obtain a probable characteristic under observation likelihood function，and the resulting likelihood
function gets the credibility of the information provided by the sensors.Then the reliability of each sensor is changed
to a mass function.Finally，multi-sensor information is combined by using evidence theory.Simulation of target recognition
shows that the results obtained have higher accuracy and reliability.

Description: cientific method refers to a body of techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.[1] To be termed scientific, a method of inquiry must be based on gathering observable, empirical and measurable evidence subject to specific principles of reasoning.[2] The Oxford English Dictionary says that scientific method is: "a method of procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses."[3]
Although procedures vary from one field of inquiry to another, identifiable features distinguish scientific inquiry from other methods of obtaining knowledge. Scientific researchers propose hypotheses as explanations of phenomena, and design experimental studies to test these hypotheses. These steps must be repeatable

Abstract For the reason of low-reliability exists in the gear fault diagnosis of traditional methods, a method
based on evidence theory hybrid diagnosis algorithm is presented. According to the fault feature vectors, two parallel
BP neural networks are used to carry on local fault diagnosis to acquire the independent evidences each other. Then
evidence theory is employed to fuse evidences, and gear fault diagnosis is fulfilled finally. Example shows that, vari-
ous faults redundant and complement information can be sufficiently used and the reliability of diagnosis is effectively
improved.

Description: 模糊证据理论 证据理论和 模糊理论的结合-Fuzzy evidence (D-S) theory is based on nonempty sets. The membership function can be determined by
comparison, increment, three division method or subjectiveness, then the function is tested by experiments. Basing on the
information granularity and probability, the D-S theory is generalized to fuzzy sets. The expected certainty and expected
probability are defined as generalized belief function and generalized plausibility function respectively. Belief function,
plausibility function and genus probability function are adopted to depict the proposition. The proposition or evidence
uncertainty is described in different aspects by the belief degree of estimation, un-rebut and conditional evidence.
