Putting low-level vision into global context: Why vision cannot be reduced to basic circuits

open access: yes
To cope with the complexity of vision, most models in neuroscience and computer vision are of hierarchical and feedforward nature. Low-level vision, such as edge and motion detection, is explained by basic low-level neural circuits, whose outputs serve ...
