Abstract(in English) | The codebook based method, which consists of a relationship of high- and low-frequency image components, achieves a high-quality image enlargement with high-frequency component augmentation. However, a codebook search process takes too much calculation time and it is not appropriate for a real-time application such as a moving image enlargement. To solve this problem, we propose a hierarchical predefined codebook to reduce the calculation cost and design a massively parallel and pipelined digital hardware architecture to realize the real-time codebook search. Simulation results show that the proposed method is 40 times faster than the ordinary method, and its FPGA implementation achieves a performance of around 54 fps for VGA size image enlargement. |
