A novel Polarimetric-Texture-Structure descriptor for high-resolution PolSAR image is presented in this paper. More precisely, a PolSAR image is represented by a tree of shapes, each of which is associated with several polarimetric and texture attributes. We first extract the texture properties and polarimetric characteristics from each shape, then use the shape co-occurrence patterns (SCOPs) to characterize...
Truncation method has been proven to be effective for computing singular minimizers or singular minimizing sequences in variational problems involving the Lavrentiev phenomenon. But truncation area involving the singular set must be selected first when using the truncation method. In this paper three numerical methods for selecting truncation area are introduced, consequently which can detect singular...
Term relation extraction is the basis of automatically building the repository of terms. The current research about term relation extraction focuses on how to obtain effective characteristics of describing the relationship. This paper presents a novel method of feature extraction based on latent relation analysis, which automatically obtains the relation characteristics from patent corpus as the features...
Latent Semantic Indexing (LSI) is an effective method in the way of feature extraction, which has been applied to many text learning tasks, such as text clustering and information retrieval. This paper thoroughly analyses the influence of term co-occurrences on the mapping of Latent Semantic Indexing and brings forward a method named pseudo document which strengthens the beneficial term co-occurrences...
Professional synthetic training (PST) is an important part in engineering education. It intends to enhance integrative experiment and designing experiment for students. It covers a wide range of professional courses and overcomes the drawbacks of traditional teaching, such as attention to the experiments of their own independent course and theorems verification. PST course based on working process...
The "left-turn with two stops" control method, being an organically combined method between signal control and roundabouts has been greatly applied in some of the Chinese cities, resulting in certain traffic and social efficiency. In the meanwhile, because of the short time in putting forward the theory, it appears, to some extent, immature up till now, especially that the essential problem...
