Purpose: This paper presents various  image indexing techniques and discusses their advantages and limitations.             Methodology: conducting a review of the literature review, it identifies three main image indexing techniques, namely concept-based image indexing, content-based image indexing and folksonomy. It then describes each technique. Findings: Concept-based image indexing is te...

In this article, a fabulous method for database retrieval is proposed.  The multi-resolution modified wavelet transform for each of image is computed and the standard deviation and average are utilized as the textural features. Then, the proposed modified bit-based color histogram and edge detectors were utilized to define the high level features. A feedback-based dynamic weighting of shap...

When performing primary reading on a newly taken radiographic examination, a radiologist often needs to reference relevant prior images of the same patient for confirmation or comparison purposes. To effectively support such prior image references, we proposed an intelligent patient image retrieval system, which includes a learning sub-system for inducing patient image retrieval knowledge, base...

Image retrieval is an important research field which has received great attention in the last decades. In this paper, we present an approach for the image retrieval based on the combination of text-based and content-based features. For text-based features, keywords and for content-based features, color and texture features have been used. Query in this system contains some keywords and an input...

several semantic image search schemes have been recently proposed to retrieve images from the web. however, the query context is regularly ignored in these techniques and hence, many of the returned images are not adequately relevant. in this paper, we make use of context to further confine the outcome of the semantic search engines. for this purpose, we propose a hybrid search engine which uti...

In an effort to achieve efficient image management in the practice of neurosurgery, a clinical data base system was designed and developed to process, store and retrieve neuroradiologic image information on hospitalized patients with the use of a local image filing system (EFPACS-500, Fuji Electric Co., Ltd). Storage and retrieval of radiographic images were studied to quantify existing procedu...
