시그니쳐를 이용한 2차원 아이코닉 이미지 색인 방법의 설계 및 구현 = Design and Implementation of Two Dimensional lconic Image Indexing Method using Signatures

다국어 초록 (Multilingual Abstract)

Spatial match retrieval methods for iconic image databases recognize an image document as several icon symbols. Therefore the iconic symbols are used as primary keys to index the image document. When a user requires content_bases retrieval of images, a spatial match retrieval method converts a query image into iconic symbols and then retrienes relevant images by accessing stored images. In order to support content_based image retrieval efficiently, we, in this paper, propose spatial match retrieval methods using signatures for iconic image databases. For this, we design new index representations of two_dimensional iconic images and explain implemented system. In addition, we comprer the conventional 9-DLT and our two_dimensional image retrieval method in terms of retrieval precision and recall ratio. We show that our method is more efficint than the conventional method.
