Accurate Image Retrieval Based on Compact Composite Descriptors and Relevance Feedback Information
Chatzichristofis, Savvas A.; Zagoris, Konstantinos; Boutalis, Yiannis S.; Papamarkos, Nikos (World Scientific Publishing Company, 2010)In this paper a new set of descriptors appropriate for image indexing and retrieval is proposed. The proposed descriptors address the tremendously increased need for e±cient content-based image retrieval (CBIR) in many ...

Text localization using standard deviation analysis of structure elements and support vector machines
Zagoris, Konstantinos; Chatzichristofis, Savvas A.; Papamarkos, Nikos (Springer, 2011)A text localization technique is required to successfully exploit document images such as technical articles and letters. The proposed method detects and extracts text areas from document images. Initially a connected ...
