论文摘要
实时捕获高光谱图像的计算机断层造影成像光谱仪（CTIS）。但是，后处理图像可能需要巨大的计算资源。因此，将其应用限制为非现实情况。为了克服这些挑战，我们开发了一种高度可行的算法，利用空间转换。为了证明我们的新算法的多功能性，我们在桌面和嵌入式图形处理单元（GPU）上开发了实现。据我们所知，我们的结果显示了报告最快的图像重建时间。
Computed Tomographic Imaging Spectrometers (CTIS) capture hyperspectral images in realtime. However, post processing the imagery can require enormous computational resources; thus, limiting its application to non-realtime scenarios. To overcome these challenges we developed a highly parallelizable algorithm that exploits spatial shift-invariance. To demonstrate the versatility of our new algorithm, we developed implementations on a desktop and an embedded graphics processing unit (GPU). To our knowledge, our results show the fastest image reconstruction times reported.
