Computational knowledge vision is emphasized as a novel perspective or field in this paper.Computational knowledge vision injects a priori knowledge into a visual perception model so that the model gains comprehension,which enables the model to learn and reason effectively to a certain extent like an ordinary adult.Computational knowledge vi-sion not only provides a"bridge"between human priori knowledge and perceptual visual machines,but also systemati-cally adapts to different levels of visual tasks on this"bridge".In addition,this paper proposes the visual hierarchy and its connection to knowledge,stating that knowledge is a justified true belief.Finally,our recent work is summarized and a new direction is proposed,which suggests that knowledge is also a thought framework in vision.
