Abstract
The importance of picture retrieval is increasing by reason of spread of multimedia content, these days. Picture retrieval with rough sketch that take automatically tagged metadata, is one of efficient methods, when we retrieve target picture of some person furthermore after retrieving with proper name. Picture retrieval with rough sketch, though, had such problems as its efficiency of retrieval dependent on quality of user's sketch. We propose we take symbolic rough sketch as query for picture retrieval. In this paper, on the assumption that we use some automatically tagged descriptors of MPEG-7, we propose transforming algorithm for matching query rough sketch appropriately. Additionally we give proof of its effectiveness.
