Investigation on advanced image search techniques
Content-based image search for retrieval of images based on the similarity in their visual contents, such as color, texture, and shape, to a query image is an active research area due to its broad applications. Color, for example, provides powerful information for image search and classification. …

CSISE: cloud-based semantic image search engine
… have especially seen the exponential growth of images on the Web, e.g., more than 6 billion in Flickr, 1.5 billion in Google image engine, and more than 1 billon images in Instagram [1]. Since big data are not only a matter of a size, but are also heterogeneous types and sources of data, image …

Smart Image Search System Using Personalized Semantic Search Method
… numbers of information on the internet nowadays, search technologies are widely used in various fields. Achieving the most relevant search result for the users becomes a big challenge now. While the traditional semantic search technologies seem to achieve the most relevant search result, however, …

Segregation similarity loss in morphological ranking of image search in histopathology
… cancers types, and the large size of Whole Slide Images (WSIs), the analysis of histopathology images is challenging. To come up with this challenge, AI algorithms, such as deep learning (DL) are used to automate image analysis efficiently and accurately. In this study, some DL methods are …

Local selection of features and its applications to image search and annotation
… for many applications, such as content-based image retrieval and automated image annotation. However, due to the existence of noisy or irrelevant features, errors introduced into similarity measurements are detrimental to the neighborhood quality of data objects. One way to alleviate the …

Comparative analysis of image search algorithm using average RGB, local color histogram, global color histogram and color moment HSV
Image retrieval forms a major problem when a large database is considered. Content Base Image Retrieval (CBIR) makes use of the available visual features of the image and helps in retrieving similar image as that of the query image. In the CBIR method, each image stored in the database has its …

Interactive Pattern Recognition Strategies for Multimedia Document Analysis and Search
Many problems in multimedia document analysis and search can be modeled as interactive prediction of semantic information. As a result, we can broadly decompose research into this area into the three critical system components: Interaction Strategies, Search/Learning Strategies and Representation. …

Eye Tracking: A Perceptual Interface for Content Based Image Retrieval
In this thesis visual search experiments are devised to explore the feasibility of an eye gaze driven search mechanism. The thesis first explores gaze behaviour on images possessing different levels of saliency. Eye behaviour was predominantly attracted by salient locations, but appears to also …

An analysis of EEG signals present during target search
Recent proof-of-concept research has appeared highlighting the applicability of using Brain Computer Interface (BCI) technology to utilise a subjects visual system to classify images. This technique involves classifying a users EEG (Electroencephalography) signals as they view images presented on a …
