摘要 针对已有的图像序列放大方法存在空间运动目标放大后细节不清晰的问题,提出基于视觉显著性的图像序列放大算法。算法首先采用视觉显著性技术获取空间运动目标区域;而后设计不同的放大策略;最后提出分区插值计算和区域能量保护方法,提升放大过程中的空间运动目标清晰度。与已有的放大算法对比的实验结果表明,提出的算法取得了更好的视觉效果和更高的平均梯度指标值、边缘强度指标值、信息熵指标值和图像功率谱指标值。 Abstract : Aiming at solving the problem of blurry details in the process of enlarging image, this paper proposed a space image sequence upscaling algorithm based on visual saliency. Firstly, it obtained space target motion regions by utilizing the visual saliency technique. Secondly, designed the different enlarging strategies according to the original resolutions and target resolu- tions. Finally, presented partition interpolation calculation and region energy protection, so the definitions of space motion tar- gets could be improved and high quality image sequences could be obtained. Compared to the existing algorithms, experiments show that the proposed algorithm achieves better visual effects and higher index values, including mean gradient, edge intensi- ty, information entropy, and image power spectrum.
