The single-feature-based background model often fails in complex scenes, since a pixel is better described by several features, which highlight different characteristics of it. Therefore, the multi-feature-based background model has drawn much attention recently. In this paper, we propose a novel multi-feature-based background model, named stability of adaptive feature (SoAF) model, which utilizes...
We propose a novel medical image segmentation algorithm by transductively inferring the labels. In this approach, superpixels are first generated to incorporate the local spatial information and also to speed up the segmentation. The segmentation task can be deemed as an unbalanced superpixels labeling problem due to the fact that the region of interest is only a small fraction compared to the whole...
This paper applies corpus linguistics techniques to study unique words in Hawks' translation of Hong Lou Meng in comparison with Yang Xianyi's translation of it. Concordance and Concapp are used to elicit data from Hong Lou Meng. By analyzing three representative unique words “dark-red”, “penny”, “mile”, which belongs to color terms, unit of money, unit of distance respectively, this paper attempts...
The descriptive capability of color images for a scene is better than that of grayscale images. Traditional registration methods to register color images convert them to grayscale ones, in which the registration precision is decreased due to the loss of color information. By extending some properties of the discrete Fourier transform to the quaternion domain, a discrete-quaternion-Fourier-transform-based...
