標題: | Architecture of MPEG-7 color structure description generator for realtime video applications | 作者: | Chang, J.-Y. Fang, H.-C. Huang, Y.-W. LIANG-GEE CHEN |
公開日期: | 2004 | 卷: | 4 | 起(迄)頁: | 2813-2816 | 來源出版物: | Proceedings - International Conference on Image Processing, ICIP | 會議論文: | 2004 International Conference on Image Processing, ICIP 2004 | 摘要: | Color structure descriptor (CSD) provides satisfactory image indexing and retrieval results among all color-based descriptors in MPEG-7. The superiority comes from the consideration of space distribution of colors. Hardware accelerator is a must because its good performance is at the expense of high computational complexity. In this paper, a design approach of speci c hardware accelerators for descriptors is explored. The characteristics of CSD algorithm are also analyzed and an ef cient architecture is proposed. The proposed architecture can generate CSD description of 256 256 image at 30 frames per second (fps). The architecture provides about 4.5 giga instructions per second (GIPS) to achieve real-time applications like assisting rate control in video coding system and circumstance change detection in surveillance system. © 2004 IEEE. |
