| 摘 要： | 本文主要研究序列图像超分辨率重建技术.本文提出了一种新的基于分块策略的超分辨率算法,由于采用分块策略,矩阵规模极大减小,且其规模与分块大小相关,而与原始序列大小无关,故能有效降低系统内存开销,提高系统处理效率.实验表明,传统多帧算法对运动估计的精度要求很高,而本文算法对此要求不高,在采用低精度运动估计技术的条件下,本文...

| Abstract: | This paper addressed the multi-frame super-resolution reconstruction.A novel block-based adaptive super resolution algorithm was proposed,and the size of matrixes was reduced greatly.The size of matrixes was related to the size of block,and independent of the size of sequence.Consequently,it could reduce the memory capacity,and improve the processing efficiency.Experiments showed that this algorithm did not have high requirement on the estimation precision of motion parameter.If estimation precision was low... |
