Image retrieval

healthcare, administration, art & commerce and academia, large collections of digital images have been created. Many of these collections are the product of digitizing existing collections of analog photographs, diagrams, drawings, paintings, and prints with which the problem of managing large databases and its repossession based on user specifications came into the picture. Due to the incredible rate, at which the size of image and video collection is growing, it is eminent to skip the subjective task of

Selection for Image Retrieval Preeti Kushwaha R.R.Welekar PG scholar, Department of CSE Professor, Department of CSE Shri Ramdeobaba College of Engineering and Management, Nagpur, India Shri Ramdeobaba College of Engineering and Management, Nagpur, India Abstract - Content based image retrieval is an image search technique which uses content of features such as colour, texture, shape, etc. to find relevant images from large collection of data according to user’s request query image on the basis

C. Image Based QA: An image-based QA approach was introduced in [11], which mainly focuses on finding information about physical objects. An image-based QA system allows direct use of an image that refers to the object. This type of systems was designed to find multimedia answers from web-scale media resources such as Flicker, Google images. D. Multimedia QA Search: Due to the increasing amount of digital information stored over the web, searching for desired information has become an essential task

substantial research attention towards image retrieval systems in the last few decades. Many great methods have been proposed, which offer numerous advantages like the following. (i) These techniques are fully automatic and avoid the manual errors of text-based systems. (ii) These techniques avoid complex tasks like annotation and also increase the accuracy of retrieval. (iii) These techniques also reduce the amount of garbage, that is, irrelevant images retrieved. (iv) These techniques, while

consideration during image retrieval (Roweis and Saul, 2000). In large multimedia databases, high-dimensional representation is computationally intensive and most users are unwilling to wait for results for a long time. Thus, for storage and retrieval efficiency concerns, dimensionality reduction in CBIR systems is necessary. Example of these techniques includes Principal Component Analysis (PCA), Independent Component Analysis (ICA) and Linear

color descriptor (DCD) [1,3,4]. A simple color similarity between two images can be measured by comparing their color histograms. The color histogram, which is a common color descriptor, indicates the occurrence frequencies of colors in the image. The color correlogram describes the probability of finding color pairs at a fixed pixel distance and provides spatial information. Therefore color correlogram yields better retrieval accuracy in comparisonto

expert system to have the effective retrieval of similar images for the given query image [1]. CBIR system is one of such experts systems that highly rely on appropriate extraction of features and similarity measures used for retrieval [10]. The area has gained wide range of attention from researchers to investigate various adopted methodologies, their drawbacks, research scope, etc [2-5, 14-18]. This domain became complex because of the diversification of the image contents and also made interesting

ABSTRACT Data mining is a popular technology for extracting interesting information for multimedia data sets, such as audio, video, images, graphics, speech, text and combination of several types of data set. Multimedia data are unstructured data or semi-structured data. These data are stored in multimedia database, multimedia mining which is used to find information from large multimedia database system, using multimedia techniques and powerful tools. This paper analyzes about the use of essential

Abstract: Ongoing expansion of digital images requires improved methods for sorting, browsing and searching through ever-growing image databases. CBIR systems are search engines for image databases, which index images according to their content. This paper presents the systematic review for CBIR systems specific to the feature extraction techniques and compares the performance and features along with limitations. Keywords: CBIR System, Image Feature Extraction, Similarity Measurement I. Introduction
