FSW material flow and phase transformation were studied at the interface of dissimilar welding of Al 6013 to Mg. Defect free butt weld was obtained when aluminum and magnesium test plates were placed in the advancing side and retreating side respectively, and the tool was placed 1 mm off the weld centerline into the aluminum side. In order to understand how the materials flow during FSW, steel ...

This paper describes an application of camera motion estimation to index cricket games. The shots are labeled with the type of shot: glance left, glance right, left drive, right drive, left cut, right pull and straight drive. The method has the advantages that it is fast and avoids complex image segmentation. The classification of the cricket shots is done using incremental learning algorithm. ...

In this paper, we discuss clustering and authoring of video shots based on a hybrid self-organizing system which uses both of video-content information and meta-data (description data) as input for Kohonen's Self-Organizing Map. Conventional contents-based methods for video shots have limitations when considering the accuracy of classi cation. We propose to improve its accuracy by generating ch...

As the foundation of the sports video annotation, shots classification is presented in this paper. Using non-supervised method the shots are clustered into defined classes (in-play, close-up and free-throw) based on the low-level features of the image (the main color and the histogram). After comparing the clusters None Euclidean Relational Fuzzy C-means (NERFCM) is applied to cluster the shots...
