Spectral filter arrays imaging exhibits a strong similarity with color filter arrays. This permits us to embed this technology in practical vision systems with little adaptation of the existing solutions. In this communication, we define an imaging pipeline that permits high dynamic range (HDR)-spectral imaging, which is extended from color filter arrays. We propose an implementation of this pipeline on a prototype sensor and evaluate the quality of our implementation results on real data with objective metrics and visual examples. We demonstrate that we reduce noise, and, in particular we solve the problem of noise generated by the lack of energy balance. Data are provided to the community in an image database for further research.
光谱滤波器阵列成像与彩色滤波器阵列有很强的相似性。这使我们能够在几乎不改变现有解决方案的情况下，将这项技术嵌入到实际的视觉系统中。在本通信中，我们定义了一种成像流程，该流程允许进行高动态范围（HDR）光谱成像，它是从彩色滤波器阵列扩展而来的。我们提出了在原型传感器上实现此流程的方法，并使用客观指标和视觉示例在真实数据上评估我们实现结果的质量。我们证明我们减少了噪声，特别是解决了由于能量不平衡产生的噪声问题。数据在一个图像数据库中提供给社区以供进一步研究。
