This research is intended to develop a layout based retrieval system for document image databases consisting of three phases: 1. At first, intelligent layout analysis algorithm has been designed to extract the layouts the document images physically with their edges and rectangles. 2. Every physically identified layout has been converted into a tree intermediary representation for indexing and s...

An effective Content-Based Image Retrieval (CBIR) system is based on efficient feature extraction and accurate retrieval of similar images. Enhanced images by using proper filter methods can also, play an important role in image retrieval in a compressed frequency domain since currently most of the images are represented in the compressed format by using the Discrete Cosine Transformation ( DCT...
