Paper Abstract

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.
