Feature selection for content-based image retrieval
In this article, we propose a novel system for feature selection,which is one of the key problems in contentbased image indexing and retrieval as well as various other researchfields such as pattern classification andgenomic data analysis. The proposed system aims at enhancing semantic image retrieval results, decreasing retrieval process complexity, and improving the overall system usability f...
متن کاملFeature Selection and Extraction for Content-Based Image Retrieval
Content-Based Image Retrieval is a technique that utilizes the visual content of an image to search for similar images in large scale image databases. The visual content of an image represents the low-level features extracted from the image. These primarily constitute color, shape and texture features. The precision of image classification and image retrieval is mainly based on image feature ex...
متن کاملFeature Selection Using Visual Saliency for Content-Based Image Retrieval
Saliency algorithms in content-based image retrieval are employed to retrieve the most important regions of an image with the idea that these regions hold the essence of representative information. Such regions are then typically analysed and described for future retrieval/classification tasks rather than the entire image itself thus minimising computational resources required. We show that we ...
متن کاملEecient Content-based Image Retrieval Using Automatic Feature Selection
We describe a self-organizing framework for content-based retrieval of images from large image databases at the object recognition level. The system uses the theories of optimal projection for optimal feature selection and a hierarchical image database for rapid retrieval rates. We demonstrate the query technique on a large database of widely varying real-world objects in natural settings, and ...
متن کاملFeature histograms for content-based image retrieval
The ever increasing amount of multimedia data creates a need for new sophisticated methods to retrieve the information one is looking for. Especially for the visual content this is still an unsolved problem. The classical approach – manual annotation – alone cannot keep up with the rapid growth of available data anymore. Thus content-based image retrieval attracted many researchers of various f...
