| Abstract(in English) | This report describes feasibility that scene thumbnail images of lecture video can be summarized using Self-Organizing Map (SOM). To extract a feature of scene thumbnail image from a lecture video, the discrete cosine transformation (DCT) was conducted for 15 segments of a image, then 3 major components from each segment were obtained. Thumbnail images were placed two-dimensionaly on the trained SOM according to each feature of the image. As results, similar images were classified on the SOM such as lecturer talking scene, presentation patterns and printed material images. Labels of presenting time provided the images, the time sequence of images also summarized on the SOM. The hybrid-type SOM which was trained with both image and term appearance features was also examined the performance of scence classfication. |
