| Abstract(in English) | The number of multimedia contents possessed by users is facing dramatic growth due to recent dissemimation of imaging device. Recently, research and development were focused on improvements in efficiency treatment, such as searching and grouping. In this paper, we focus on digital photo album in which allows searching and grouping, and conducts fundamental research on transferring its functions towards mobile devices. Now, the function is not practically implemented due to technical difficulties with meta-data generation processing. However, it is highly likely that mobile device suppliers will provide various services based on meta-data, and hance we will mainly discuss with meta-data generation processing system in this research. The constructed system here produces meta-data standardized by MPEG-A Photo Player, and it is aimed to generate the data in 1 second for the purpose of mobile device implementation. With regarding to the most significant bottleneck; cluster substitution, we will resolve this problem by speeding up Radon-transformation and reducing image size, in order for reducing through-put. On the other hand, we introduce custom hardware to establish histogram, which leads the system to enhance running time and reach the data generation within 1 second. Therefore, our system runs 0.87 second, it satisfies the constraint: within 1 second. |
