This study investigated music video viewers’ characteristics and their preference evaluation criteria. We had detailed interviews based on the evaluation grid method with ten participants. All participants watch music videos frequently. Our participants could be divided into following two types: (1) viewers: they emphasized the importance of the singer(s) singing the song in their preference evaluation criteria. (2) viewers: they insisted that the images were the high-priority parameters in their preference evaluation. It is noteworthy that their preference criteria and viewing style were affected by whether they prefer Japanese or English songs.

As virtual economies begin to interact more with real world economies, it is important to consider the in-game activities that players engage in, which create and transfer game currency. Specifically, we examine products and services that players offer to each other within MMORPGs. We use Bartle’s taxonomy of player types to illustrate the different behavioral approaches players have in consuming these products and services. We introduce the term virtual consumption to describe these in-game exchanges and highlight the need for further research into this phenomenon.

This paper presents an image retrieval method based on keyblocks combing with interest points, furthermore the generation of codebook is also utilized to enhance the retrieval performance, where the balance between the retrieved precision and time cost can decide the codebook size of this CBIR system. Finally, the proposed method is compared with the method that only depends on interest points or keyblocks.

We propose an image mosaic method based on tile template. Compared with a conventional mosaic which is comprised of the circle or the square tiles, our approach uses the arbitrary shaped tiles. But an arbitrary shaped tile leaves the excessive gap between tiles in the mosaic construction. Then the gap makes it difficult to preserve the fine detail of an original image. Our approach controls overlap between tiles to minimize the gap by using the mask technique and adopts stackable technique to represent the fine detail of a source image automatically.
