HIPPA - Hyperspectral and RGB imaging of wound-inoculated apples with postharvest pathogens

This collection is part of the HIPPA project, which investigates physiological disorders, mechanical damage and fungal diseases affecting apple fruit at harvest and during postharvest using hyperspectral imaging, RGB imaging and spectroscopy. This collection contains RGB images and hyperspectral images of wound-inoculated apples infected with eight different pathogens and corresponding control samples. Healthy-looking apples were manually surface-sterilized and inoculated with spore suspensions. To cover all cultivars and pathogens, apples were prepared and acquired in groups referred to as 'batches' at different timestamps. Each batch contains apples from one specific cultivar and includes a subset of pathogen treatments together with control samples; each batch generally contains approximately 24 apples per included treatment and approximately 24 control apples. Each STAC Item represents one apple sample at one specific day post-inoculation. Item identifiers follow the pattern apple_{sample_id}_dpi{dpi:02d}, for example apple_57000_dpi03. The acquisition setup is an enclosed space of approximately 1 x 1 m, equipped with a lighting system, a rotating platform and multiple optical instruments measuring the apple surface. Acquisitions are performed in the Eurac Research - Center for Sensing Solutions laboratories. The Collection spatial extent represents the general area of origin of the apple samples, while Item geometries represent the laboratory acquisition location.本数据集隶属于HIPPA研究项目，该项目借助高光谱成像 (hyperspectral imaging)、RGB成像 (RGB imaging)与光谱学 (spectroscopy)技术，针对采收期及采后阶段苹果果实面临的生理紊乱、机械损伤与真菌病害展开研究。本数据集涵盖了被8种不同病原菌侵染的伤口接种苹果的RGB图像与高光谱图像，以及对应的对照样本。外观健康的苹果经人工表面灭菌后，通过孢子悬浮液完成接种。为覆盖全部苹果品种与病原菌类型，研究人员按不同时间节点将制备完成的苹果划分为若干批次 (batches)开展图像采集工作。每个批次仅对应单一特定品种的苹果，包含一组病原菌处理样本与对照样本；通常每个处理组与对照组各配置约24个苹果样本。每个STAC项 (STAC Item)代表接种后某一特定天数的单个苹果样本。项标识符遵循apple_{sample_id}_dpi{dpi:02d}格式，示例为apple_57000_dpi03。采集装置设于面积约1×1米的封闭空间内，配备照明系统、旋转平台与多台用于检测苹果表面的光学仪器。所有采集工作均在欧拉克研究院 (Eurac Research)传感解决方案中心实验室完成。数据集的空间范围代表苹果样本的整体来源区域，而各STAC项的几何信息则对应实验室中的采集位置。
