Metric Indexing for Content-Based Medical Image Retrieval
ثبت نشده
چکیده
The paper proposes an indexing method for fast content-based retrieval in an image repository. The method is based on a metric-indexing strategy that avoids to calculate the distance from the query to all the images in the repository. The proposed indexing method is tested on a pathology image collection comparing its performance against sequential scaning indexing. The results show that the metric indexing method improves the access time by a factor of 10, without a significant sacrifice on precision.

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...

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...
متن کاملEfficient Matching and Indexing of Graph Models in Content-Based Retrieval
ÐIn retrieval from image databases, evaluation of similarity, based both on the appearance of spatial entities and on their mutual relationships, depends on content representation based on Attributed Relational Graphs. This kind of modeling entails complex matching and indexing, which presently prevents its usage within comprehensive applications. In this paper, we provide a graphtheoretical fo...
متن کاملThe Metric Histogram: A New and Efficient Approach for Content-based Image Retrieval
This paper presents the metric histogram, a new and efficient technique to capture the brightness feature of images, allowing faster retrieval of images based on their content. Histograms provide a fast way to chop down large subsets of images, but are difficult to be indexed in existing data access methods. The proposed metric histograms reduce the dimensionality of the feature vectors leading...
متن کاملHierarchical linear subspace indexing method
Traditional multimedia indexing methods are based on the principle of hierarchical clustering of the data space where metric properties are used to build a tree that can then be used to prune branches while processing the queries. However, the performance of these methods will deteriorate rapidly when the dimensionality of the data space is increased. We describe a new hierarchical linear subsp...
