Semantic Image Interpretation - Integration of Numerical Data and Logical Knowledge for Cognitive Vision
Semantic Image Interpretation (SII) is the process of generating a structured description of the content of an input image. This description is encoded as a labelled direct graph where nodes correspond to objects in the image and edges to semantic relations between objects. Such a detailed …
