Tensor field design plays an essential role in various computergraphics applications. One of the main challenges in field design is how to obtain a smooth field preserving meaningful singularities presented in the original scene. Compared with well-studied point singularities, line singularities, commonly occur on object boundaries and occluding contours, are not exploited enough for field design in previous work. In this paper, we discuss the definition of line singularities, and introduce a line-singularity-based interactive tensor field design method, allowing the user to design feature-preserving tensor fields with less effort and to preserve both input singularities and user-specified stroke directions. To avoid introducing extra interaction burdens to the user, our method automatically locates line singularities using a geodesic-based segmentation. We demonstrate the capabilities of our method on tensor field design with various nonphotorealistic rendering applications and the real-time performance accelerated on GPU.

this paper presents the results of a study conducted on integrating interactive computeraided learning into teaching English as a Second Language to adult learners in Sri Lanka. Two sample groups of similar language competency levels preparing for an international examination were selected to assess the effectiveness of computeraided language learning in enhancing language skill,. While the duration of the course and material supplied were similar, one group relied entirely on course material and face-to-face teaching, whereas the second group was additionally introduced to computeraided language learning activities. At the end of the course the students of the second group showed remarkable improvement in their language skills securing high band scores at the examination

this paper propose an improved supervised method for retinal vessel segmentation based on Extreme Learning Machine (ELM). Firstly, a 36-D feature vector is extracted for each pixel of the fundus image consisting of local features, morphological features and divergence of vector fields. then a matrix for pixels of the training set using the feature vector and the manual segmentation is constructed as the input of the ELM. Finally a classifier is obtained to segment the retinal vessels. the method is evaluated withthe DRIVE database and the average accuracy is 0.9581. And the running time is greatly decreased by using ELM. It is applicable for computer-aided diagnosis and disease screening.
