来自人眼诞生地的自然图像
Natural images from the birthplace of the human eye
摘要：
在这里，我们介绍了一个数据库的校准自然图像公开提供通过一个易于使用的Web界面。使用尼康D 70数码单反相机，我们获得了约5000个六百万像素的博茨瓦纳奥卡万戈三角洲，热带稀树草原栖息地类似于人类眼睛被认为已经进化的图像。一些图像序列是在跟踪狒狒部队时不系统地捕获的，而另一些则是为了改变单个参数，如光圈，物体距离，一天中的时间或地平线上的位置。图像可在原始RGB格式和灰度。图像也可以以与人类视锥光感受器的生理学相关的单位提供，其中像素值表示对长（L）、中（M）和短（S）波长敏感的视锥每秒光异构化的预期数量。该数据库是在知识共享署名-非商业性非移植许可下分发的，以促进计算机视觉，感知的心理物理学和视觉神经科学的研究。
英文摘要：
Here we introduce a database of calibrated natural images publicly available through an easy-to-use web interface. Using a Nikon D70 digital SLR camera, we acquired about 5000 six-megapixel images of Okavango Delta of Botswana, a tropical savanna habitat similar to where the human eye is thought to have evolved. Some sequences of images were captured unsystematically while following a baboon troop, while others were designed to vary a single parameter such as aperture, object distance, time of day or position on the horizon. Images are available in the raw RGB format and in grayscale. Images are also available in units relevant to the physiology of human cone photoreceptors, where pixel values represent the expected number of photoisomerizations per second for cones sensitive to long (L), medium (M) and short (S) wavelengths. This database is distributed under a Creative Commons Attribution-Noncommercial Unported license to facilitate research in computer vision, psychophysics of perception, and visual neuroscience.
