Artery and vein (AV) classification of retinal images is a key to necessary tasks, such as automated measurement of arteriolar-to-venular diameter ratio (AVR). This paper comprehensively reviews the state-of-the art in AV classification methods. To improve on previous methods, a new Local Binary Pattern-based method (LBP) is proposed. Beside its simplicity, LBP is robust against low contrast an...

Many of our most common diseases are complex disorders, run in families, but they lack the simple inheritance patterns characteristics of single gene disorders. Complex diseases have low heritability compared to single gene disorders. Understanding the genetic factors underlying common disorders is a difficult but critical task because each genetic and environmental factor can contribute toward...

This paper benchmarks the simple Local Binary Pattern (LBP) approach in the supervised texture segmentation problems of the recent comparative study of Randen and Husøy. A multi-predicate version of LBP is proposed, making our approach even more powerful for images containing textures at multiple scales.

Recent developments in face analysis showed that local binary patterns (LBP) provide excellent results in representing faces. LBP is by definition a purely gray-scale invariant texture operator, codifying only the facial patterns while ignoring the magnitude of gray level differences (i.e. contrast). However, pattern information is independent of the gray scale, whereas contrast is not. On the ...

Research in automatic facial expression recognition has permitted the development of systems discriminating between the six prototypical expressions, i.e. anger, disgust, fear, happiness, sadness and surprise, in frontal video sequences. Achieving high recognition rate often implies high computational costs that are not compatible with real time applications on limited-resource platforms. In or...

Quality assessment in carpet manufacturing is performed by humans who evaluate the appearance retention (AR) grade on carpet samples. To quantify the AR grades objectively, different research based on computer vision have been developed. Among them Local Binary Pattern (LBP) and its variations has shown promising results. Nevertheless, the requirements of quality assessment on a wide range of c...

BACKGROUND Recent evidence suggests that diet modifies key biological factors associated with the development of depression; however, associations between diet quality and depression are not fully understood. We performed a systematic review to evaluate existing evidence regarding the association between diet quality and depression. METHOD A computer-aided literature search was conducted usin...

In distributed systems, objects are transported and addressed via network connections. A protocol for object transportation helps to cross the mismatch between objects with state and behavior, and a flat transport presentation. There are different strategies for approaching such a protocol definition. The choice of an appropriate process does not only have a technical impact, but also determine...

Change and evolution of business and technology imply change and evolution of development processes. Besides that for a certain enterprise and/or project we will usually integrate elements from a variety of existing process models, comprising generic standards as well as specific development methods. In this paper we propose a Process Framework which is modularly structured on the basis of the ...

BACKGROUND Although 'unhealthy' diet is a well-known risk factor for non-communicable diseases, its relationship with socio-economic status (SES) has not been fully investigated. Moreover, the available research has largely been conducted in countries at high levels of human development. This is the first study to examine relationships among dietary patterns and SES of children from countries s...
