The Similarity of Images Generated by Bag Context Shape Grammars
Publication Year: 2020,Page(s):1 - 6
Shape grammars are a class of grammar in formal language that uses spatial rules to generate images. Shape grammars generate images in a way that is not always regulated. That is, they generate images without considering the similarity between them. This is largely because they are context free. As such, the application of a rule is not controlled during derivation. Bag Context Shape Grammars (BCS...Show More
