In this paper, we focus on the problem of unsupervised clustering which allows automatic setting of optimal clusters number. We present a generalization of the competitive agglomeration clustering algorithm firstly introduced in [1]. This generalization is inspired by the regularization theory and suggests a new schema for using various cluster validity criteria continuously proposed in the lit...

Digital visual libraries have currently available huge amounts of content in unstructured, nonindexed form. Since these collections keep growing fast, retrieving specific images is becoming extremely difficult. It is too slow to linearly search all the stored feature vectors to find those that satisfy the query criteria. Scalability is crucial for an image retrieval system to be practical and r...

The Hough transform is a well-established scheme for detecting digital line components in a binary edge image. A key to its success in practice is the notion of voting on an accumulator array in the parameter plane. This paper discusses computational limitation of such voting-based schema under the constraint that all possible line components in a given image must be reported. Various improveme...

In this paper we describe an indexing, querying and browsing system for online images based on the PNG (Portable Network Graphics) image format and its ability to embed structured metadata within the image. First we describe a Java application which enables the computer-assisted generation and editing of Dublin Core-based metadata descriptions for digital images and the annotation of regions wi...

This article presents a novel AAC communication aid based on semantic rather than syntactic schema, leading to more natural message construction. Users interact with a two-dimensional spatially organized image schema, which depicts the semantic structure and contents of the message. An overview of the interface design is presented followed by discussion of its implications and limitations. Pote...

and Body Image in 9to 12-Year-Old Girls: The Role of Appearance Schemas. Journal of Clinical Child & Adolescent Psychology (Impact Factor: 1.92). Definition: Gender schema theory refers to the theory that children learn about what it means to be male and female from the culture in which they live. According. It is important to have a clear definition of each construct psychological androgyny. S...

Billions of new images are generated daily. However, the management and exchange of the associated metadata remains cumbersome. Therefore, the Joint Photographic Experts Group (JPEG) has recently promoted a new set of technologies enabling the interoperability between image repositories and/or their clients to an international standard. JPSearch is a suite of specifications that supports the en...

Mainly task of optimizing design of Industrial Photogrammetric Network with Variant Interior Elements (IPNVIE) is to provide a schema for a set of interior relatively problems in a photographic task. It includes: how to choose cameras, design measure marks, choose obtaining data schema, choose measurement method of image coordinates and schema of analytic process of photographic measurement, an...
