A new method named multiple-point geostatistics (MPS) which originated from geoscience allows extracting the characteristics and structures from training images and anchoring them to the simulated regions. The 3D reconstruction of porous media is quite significant to the study of mechanisms of fluid flow in porous media. Therefore, a method using a real 2D micro-CT image and MPS to reconstruct the...
A relatively unexplored problem in facial expression analysis is how to select the positive and negative samples with which to train classifiers for expression recognition. Typically, for each action unit (AU) or other expression, the peak frames are selected as positive class and the negative samples are selected from other AUs. This approach suffers from at least two drawbacks. One, because many...
In this paper a novel linear regression model is proposed to mine related queries from query logs. Three types of association relationships between queries are identified and leveraged in our model, which include query session co-occurence, URL-clicked sharing and text similarity. Previous work directly applies part of these relations, which may be largely affected by the noise in query logs, such...
