The paper focuses on the image segmentation methods based on histogram analysis, and proposes a novel image segmentation approach based on cloud model. Firstly, the paper introduces the basic principles of cloud model. Similar to type-2 fuzzy sets, cloud model considers the uncertainty of membership grades. But it also considers the randomness of them. It is a new kind of uncertain model which is...
Many interpolation methods were proposed to predict or reconstruct unknown information. However, when the conditional data are quite few or even there are no conditional data, predicted results are often poor. Originally, a method called multiple-point geostatistics (MPS) originated from geostatistical fields and it allows extracting multiple-point structures from training images, after that MPS can...
Multiple-point geostatistics (MPS) simulation originates from geostatistical fields and allows extracting multiple-point structures from training images, after that MPS can copy these structures to the regions to be simulated. Porosity is quite significant to the characterization and prediction of transport properties. To simulate the porosity value, a porosity simulation method using continuous MPS...
