Images contain step edges, line features and many feature types that are somewhere between the two. Traditional gradient based edge operators are tuned to detect step edges, and hence are unable to properly detect and localize other feature types. The Phase Congruency detector is used as a tool to identify the different feature types found in images. It is shown that there is a continuum of fea...

BACKGROUND An accurate accounting of service use is necessary to understand use patterns and outcomes. Yet such an accounting remains challenging, in part because of the reliability and validity of the collection method and sources. OBJECTIVES This study describes 2 methods of data collection: self-report and the retrieval of provider records. We report on the effort, yield, and challenges of...

There are no known studies that have been conducted focusing on the congruency or discrepancy of pre service agricultural education programmes in relation to secondary school agriculture teaching in Zimbabwe. The purpose of this study was therefore to make a qualitative investigation on the contribution of pre service agricultural education training programmes to the teaching of high school Agr...

Purpose – This paper aims to test a theoretical framework that explains arousal congruency effects on consumer perceptions of intrinsically pleasant service environments. Design/methodology/approach – A 3 (low and high target-arousal manipulation plus control group) by 3 (low, medium and high actual arousal) true experimental design was used to test our research hypotheses in a café context. Th...

Conceptual congruency effects have been interpreted as evidence for the idea that the representations of abstract conceptual dimensions (e.g., power, affective valence, time, number, importance) rest on more concrete dimensions (e.g., space, brightness, weight). However, an alternative theoretical explanation based on the notion of polarity correspondence has recently received empirical support...

This paper presents a 3-level RDWT biometric watermarking algorithm to embed the voice biometric MFC coefficients in a color face image of the same individual for increased robustness, security and accuracy. Phase congruency model is used to compute the embedding locations which preserves the facial features from being watermarked and ensures that the face recognition accuracy is not compromise...

The study tests the hypothesis of an embodied associative triangle among relative tone pitch (i.e., high or low tones), vertical movement, and facial emotion. In particular, it is tested whether relative pitch automatically activates facial expressions of happiness and anger as well as vertical head movements. Results show robust congruency effects: happiness expressions and upward head tilts a...

The current study addressed modality effects in a web-based Concealed Information Test (CIT) by asking participants to encode, and later conceal, crime-related details. Items were encoded tested verbally or pictorially. A pilot (N = 73) preregistered (N = 158) showed robust interaction between encoding testing modality: that the same associated with better detection. Moreover, recognition of it...

Many tasks are conducted under time and performance constraints, but the mood-congruency of real situations rarely translate to training environments. The ability to perceive affect (emotion and mood states) is essential in understanding how the trainee is reacting to the scenario. This affective data can be used to modify the challenge and flow of scenario or the amount/frequency of support/di...

Purpose This study aims to develop an understanding of how customers a physical retail store valuate receiving location-based mobile phone messages when they are in proximity the store. It proposes and tests model relating two benefits (personalization location congruency) sacrifices (privacy concern intrusiveness) message value perceptions visit attitudes. Design/methodology/approach The uses ...
