A compact optical correlator applicable to the retrieval of colour and texture as well as shape information was developed. A new technique for retrieving colour and texture information by using a slot-in-type compact joint-transform correlator (JTC) with minimum size (140 (W) × 220 (L) × 40 mm (H)) was developed. The developed techniques were used to retrieve images of fruits and vegetables, taken by the digital camera. The developed technique can retrieve images of certain fruits, such as an apple, from images of many different fruits and vegetables. It will open up a new area of retrieval techniques for ambiguous images based on shape, colour and texture information.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
