Color-Orientation Indexing
نویسندگان
چکیده
Observing the development of content based image retrieval systems hindered by the lack of eecient image representations, color histogram based indexing techniques have been used quite successfully. Though their performance strongly depends on illumination conditions being controlled, there has been only small eeort to make them invariant to illumination. By introducing color{orientation histograms we present an integrated representation for color and local orientation, achieving robustness to several illumination conditions for free. Our method involves steerable lter techniques and Lab{color space conversion.

Content Based Radiographic Images Indexing and Retrieval Using Pattern Orientation Histogram
Introduction: Content Based Image Retrieval (CBIR) is a method of image searching and retrieval in a database. In medical applications, CBIR is a tool used by physicians to compare the previous and current medical images associated with patients pathological conditions. As the volume of pictorial information stored in medical image databases is in progress, efficient image indexing and retri...
متن کاملColor and Shape Based Indexing Using Scale-space Representations
Performance of an image or video database is directly related to indexing performance. Proposed indexing methods usually rely on low-level features such as color, texture and shape information extracted from an image or a key-frame selected within a shot, which are very sensitive to small changes in intensity or lightning conditions. In this study, we show that one can extract more robust and r...
متن کاملOrientation and Scale Invariant Text Region Extraction in WWW Images
Text extraction from a web image is important for web indexing because the text can contain a key information of the web. This paper presents a method to detect a text with various orientation and multifont sizes in a web image. The proposed method consists of three steps; 1) color reduction of low resolution web image by a spatial merging algorithm, 2) extraction of character candidates by fin...
متن کاملA Novel Local Structure Descriptor for Color Image Retrieval
A novel local structure descriptor (LSD) for color image retrieval is proposed in this paper. Local structures are defined based on a similarity of edge orientation, and LSD is constructed using the underlying colors in local structures with similar edge direction. LSD can effectively combine color, texture and shape as a whole for image retrieval. LSH integrates the advantages of both statisti...
متن کامل3-D object recognition by matching the total view information
In this paper we present a complete 3-D object recognition system. The system has the following components: 1) The applied, viewer centered extended surface normal image (ESNI) representation is new and promising. 2) Photometric Stereo Method (PSM) we have integrated specular highlight elimination and we have developed a method, that combines dense gradient information and a line drawing of the...
