Content-based image visualization

Abstract: The proliferation of content based image retrieval techniques has highlighted the need to understand the relationship between image clustering based on low-level image features and image clustering made by human users. In conventional image retrieval systems, images are typically characterized by a range of features such as color, texture, and shape. However, little is known to what extent these low-level features can be effectively combined with information visualization techniques such that users may explore images in a digital library according to visual similarities. The authors compare and analyze a number of Pathfinder networks of images generated based on such features. Salient structures of images are visualized according to features extracted from color, texture, and shape orientation. Implications for visualizing and constructing hypermedia systems are discussed.

Relevance Feedback in Content-Based Image Retrieval: A Survey

Abstract: In content-based image retrieval, relevance feedback is an interactive process, which builds a bridge to connect users with a search engine. It leads to much improved retrieval performance by updating a query and similarity measures according to a user’s preference; and recently techniques have matured to some extent. Most previous relevance feedback approaches exploit short-term learning (intraquery learning) that deals with the current feedback session but ignoring historical data from other users, which potentially results in a great loss of useful information. In the last few years, long-term learning (inter-query learning), by recording and collecting feedback knowledge from different users over a variety of query sessions has played an increasingly important role in multimedia information searching. It can further improve the retrieval performance in terms of effectiveness and efficiency. In the published literature, no comprehensive survey of both short-term learning and long-term learning RF techniques has been conducted. To this end, the goal of this chapter is to address this omission and offer suggestions for future work.

Image Clustering Using Color and Texture

Abstract: With the advancement in image capturing device, the image data been generated at high volume. Grouping images into meaningful categories to reveal useful information is a challenging and important problem. Content based image retrieval address the problem of retrieving images relevant to the user needs from image databases on the basis of low-level visual features that can be derived from the images. Due to semantic gap between low-level image features and the richness of human semantics, a challenge with image contents is to extract meaning from the data they contain. Image mining deals with the extraction of implicit knowledge, image data relationship, or other patterns not explicitly stored in the images. Proposed framework focuses on color and texture as feature. Color Moment and Gabor filter is used to extract features for image dataset. K-Means and Hierarchical clustering algorithm is applied to group the image dataset into various clusters

Design of Feature Extraction in Content Based Image Retrieval (CBIR) using Color and Texture

Abstract: Retrieval of images based on visual features such as color, texture and shape have proven to have its own set of limitations under different conditions. Various techniques have been implemented using these features like fuzzy color histogram, Tammura texture etc. In this paper we propose a novel method with highly accurate and retrieval efficient approach which will work on large image database with varied contents and background.

Deeply learnt hashing forests for content based image retrieval in prostate MR images

Abstract: Deluge in the size and heterogeneity of medical image databases necessitates the need for content based retrieval systems for their efficient organization. In this paper, we propose such a system to retrieve prostate MR images which share similarities in appearance and content with a query image. We introduce deeply learnt hashing forests (DL-HF) for this image retrieval task. DL-HF effectively leverages the semantic descriptiveness of deep learnt Convolutional Neural Networks. This is used in conjunction with hashing forests which are unsupervised random forests. DL-HF hierarchically parses the deep-learnt feature space to encode subspaces with compact binary code words. We propose a similarity preserving feature descriptor called Parts Histogram which is derived from DL-HF. Correlation defined on this descriptor is used as a similarity metric for retrieval from the database. Validations on publicly available multi-center prostate MR image database established the validity of the proposed approach. The proposed method is fully-automated without any user-interaction and is not dependent on any external image standardization like image normalization and registration. This image retrieval method is generalizable and is well-suited for retrieval in heterogeneous databases other imaging modalities and anatomies.
