Complex named entities can refer to specific objects, literal obvious characteristics, which are closely related entities in our daily life, study and work. Named entity recognition complex cannot form only an important data resources on the Internet to provide a basis for information extraction, but also leverage search engines to help to understand the user's query intent, which gives targeted,...
Character segmentation and recognition are two difficult key steps in extracting literal information from images. This paper proposes a method for effective segmentation and recognition of characters in complicated graphical contexts of line drawings. Text pixels are first separated from intersecting non-text objects with the holistic graphic recognition algorithm, and then character boxes are grouped...
In our earlier study, the property of L2-gain robust control is incorporated into the direct adaptive fuzzy control design with the use of the compensative controller. The tracking control performance is guaranteed. In the study, we further employ the L2-gain property to improve the adaptive law design. Due to the L2-gain control property, the approximate error of the fuzzy system is estimable, and...
A semi-automatic 3D roof reconstruction method is proposed in this paper. It consists of two components: automatic recognition of 2D plane drawings and interactively ldquopullingrdquo or ldquopushingrdquo the recognized results. Only a limited number of reconstruction operations are needed to generate various types of 3D roofs, making the method efficient.
In this study, an idea to the self-tuning sliding mode controller design is proposed. The proposed controller not only reduces the chatting phenomenon, but also needs less the system bounds than traditional sliding mode controllers do. The proposed self-tuning sliding mode controller can be viewed as an improved hitting controller. Besides, in order to resolve the parameter selection problem, the...
