大规模光源数据集
收藏资源简介:
该大规模光源数据集由米兰比可卡大学研究团队构建,旨在为相机色彩校正研究提供全面的光谱功率分布资源。数据集包含1,473个具有不同光谱特性的光源,覆盖CIE xy色度图的广泛区域,数据来源于多个公开光谱测量数据集,包括标准光源、荧光灯和LED照明。创建过程通过聚合多个公开数据源获得438个原始光源,并采用凸线性插值方法在测量光源对之间合成额外样本,最终形成均匀覆盖色度空间的数据集。该数据集主要应用于计算摄影和图像信号处理领域,专门用于解决复杂照明条件下相机色彩校正的挑战,特别是针对非普朗克光源和光谱复杂LED照明的色彩保真度问题。
This large-scale light source dataset was constructed by the research team from the University of Milan-Bicocca, aiming to provide a comprehensive spectral power distribution resource for camera color correction research. The dataset contains 1,473 light sources with diverse spectral characteristics, covering a wide range of the CIE xy chromaticity diagram. The data is sourced from multiple public spectral measurement datasets, including standard light sources, fluorescent lamps, and LED lighting. In the creation process, 438 original light sources were obtained by aggregating multiple public data sources, and convex linear interpolation was used to synthesize additional samples between pairs of measured light sources, ultimately forming a dataset that uniformly covers the chromaticity space. This dataset is mainly applied in the fields of computational photography and image signal processing, and is specifically designed to address the challenges of camera color correction under complex lighting conditions, especially the color fidelity issues for non-Planckian light sources and spectrally complex LED lighting.
由于提供的README文件中没有关于数据集的具体信息(如名称、描述、用途、规模、格式等),仅包含一个占位说明“The code will be released upon acceptance.”,因此无法生成有效的数据集详情总结。
