A Novel Feature Extraction Method Based on Segmentation over Edge Field for Multimedia Indexing and Retrieval
نویسندگان
چکیده
In this work we focused on visual content extraction. Digital images have some basic features, such as texture, colour and shape. Through low-level bit processing, and using colour intensity changes across pixels, we try to achieve some form of mid-level meaningful description of the image. Starting from the well-known Canny Edge algorithm we convert the image map to an edge map. From the edges, and performing analysis based on perceptual rules, we achieve a segmentation of the image, which is proved sound for content-based indexing and retrieval purposes.

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 کاملA Novel Shape Descriptor over Multi - Scale Edge Field : 2 D Walking Ant Histogram
A generic shape descriptor, which can be extracted from the major object edges in an automatic way and used for the content-based retrieval in multimedia databases, is presented. Via adopting a multi-scale approach over the edge field where the scale represents the amount of simplification, the most relevant edge segments, as we refer to subsegments, which eventually represent the major object ...
متن کاملSegmentation Improvement of High Resolution Remote Sensing Images based on superpixels using Edge-based SLIC algorithm (E-SLIC)
The segmentation of high resolution remote sensing images is one of the most important analyses that play a significant role in the maximal and exact extraction of information. There are different types of segmentation methods among which using superpixels is one of the most important ones. Several methods have been proposed for extracting superpixels. Among the most successful ones, we can r...
