Human vision is naturally more attracted by some regions within their field of view than others. This intrinsic selectivity mechanism, so-called visual attention, is influenced by both high- and low-level factors; such as the global environment (illumination, background texture, etc.), stimulus characteristics (color, intensity, orientation, etc.), and some prior visual information.

人类视觉系统天生会对视野内的部分区域产生更强的注意力偏向。这种内在的选择性机制即所谓的视觉注意力（visual attention），同时受高低层级因素共同影响：例如全局环境（光照、背景纹理等）、刺激特征（色彩、亮度、朝向等）以及部分先验视觉信息。
