The Search_2 dataset

The Search_2 dataset consists of <em>(1)</em> a set of 44 high-resolution digital color images of different complex natural scenes, <em>(2)</em> the ground truth corresponding to each of these scenes, and <em>(3)</em> the results of psychophysical experiments on each of these images. The images in the Search_2 dataset are a subset of a larger set that was used in a visual search and detection experiment. Each scene (image) contains a single military vehicle that serves as a search target. Areport describes the images in detail, and presents the corresponding ground truth and observer data. The image dataset, an Excel file with the ground truth and observer data, and a copy of this report are included in the dataset. The complete dataset can be used to validate <em>(1)</em> digital metrics that compute the visual distinctness (contrast, conspicuity, or saliency) of targets in complex scenes, and (<em>2)</em> models of human visual search and detection.

Search_2数据集由三部分构成：(1) 44幅涵盖不同复杂自然场景的高分辨率彩色数字图像；(2) 对应每幅场景的真实标注（ground truth）；(3) 针对每幅图像开展的心理物理实验结果。该数据集收录的图像是某视觉搜索与检测实验所用更大规模图像集合的子集，每幅场景图像中均包含一个作为搜索目标的军用车辆。本报告对数据集内的图像进行了详细介绍，并给出了对应的真实标注与观察者实验数据。数据集包含图像数据集、一份载有真实标注及观察者数据的Excel文件，以及本报告的副本。完整的Search_2数据集可用于验证两类研究内容：(1) 用于计算复杂场景中目标视觉辨识度（对比度、醒目度或显著性）的数字指标；(2) 人类视觉搜索与检测模型。
