最近，人们对自然图像的性质重新产生了兴趣。它们的统计数据不仅在图像压缩中很重要，而且对于生物学中感官处理的研究也很重要，这可以被视为满足某些“设计标准”。本文总结了以前的工作，图像统计，并提出了我们自己的数据。也许自然图像最显著的特性是尺度不变性。我们目前的数据来支持这一说法，以及在自然场景中的层次不变性的证据。这些对称性提供了一个强大的自然图像的描述，因为它们极大地限制了允许的分布类。
Recently there has been a resurgence of interest in the properties of natural images. Their statistics are important not only in image compression but also for the study of sensory processing in biology, which can be viewed as satisfying certain 'design criteria'. This review summarizes previous work on image statistics and presents our own data. Perhaps the most notable property of natural images is an invariance to scale. We present data to support this claim as well as evidence for a hierarchical invariance in natural scenes. These symmetries provide a powerful description of natural images as they greatly restrict the class of allowed distributions.
