In this paper, an efficient strategy is proposed to design the automatic steering controller for trajectory tracking of unmanned vehicles, which is robust with respect to the inherent nonlinearities and uncertainties of vehicles. The proposed automatic steering controller consists of a feedback part and a feedforward part. First, a fuzzy controller is proposed as the feedback part, and the parameters...
The researches on Human Visual System (HVS) lead to more comprehension in the visual perceptibility of human eyes and make dramatic contribution in image quality assessment. However, few perceptual hashing algorithms take the visual perceptibility into account. In this paper, we propose a new visual threshold adjustable perceptual hashing method under the guidance of Watson's visual model. This method...
A method extended from a constrained Delaunay algorithm, which generates the multi-tissue tetrahedral meshes for segmented medical images, is proposed in this paper. With an external boundary surface and internal sampling points, the anatomical objects are tetrahedralized homogenously. A new tissue-labeling scheme is utilized to assign the distinct tissue types of the additional inserted points and...
3D face data have been increased recently with the development of 3D data acquisition technology. 3D face has extensive applications. A proper coordinate system defined on faces is sometimes necessary. However, building a canonical coordinate system for all the 3D faces presenting the physiological vertical direction of human face is still an open question. In this paper, we propose a new 3D face...
Posterior probability is mostly used for pronunciation evaluation. This paper introduces pronunciation space models to calculate posterior probability replacing traditional phone-based acoustic models, which makes the calculated posterior probability more precise. Pronunciation space models are constructed using unsupervised clustering method guided by human scores and phone-level posterior probability...
This study was undertaken to implement the three-dimensional (3D) reconstruction of the intraneural structure in the upper limb peripheral nerves. Three fresh cadaver peripheral nerves (one median, one ulnar and one radial nerve) were located with human hair, embedded in OCT, sectioned consecutively every 100 mum at a 20 mum thickness. Then all slices were stained with the acetylcholinesterase histochemical...
