Segmentation Quality for Augmented Reality: An Objective Metric
(Ieee, 2015-01-01)
Assessment the quality of segmentation algorithms considering the user perception is an important problem in Computer Vision. For this purpose a metric must take into account the impact of different types of errors displayed ...
PAD: a perceptual application-dependent metric for quality assessment of segmentation algorithms
(Springer, 2019-11-01)
Extracting elements of interest from video frames is a necessary task in many applications, such as those that require replacing the original background. Quality assessment of foreground extraction algorithms is essential ...
Market segmentation under the choice modelling framework
(Universidad del Desarrollo. Facultad de Economía y Negocios, 2021)
This thesis examines market segmentation from an economic perspective by drawing on the choice modelling framework. The market segmentation literature focuses on providing information to marketers about customers, especially ...
Fostering segmental pronunciation through self-assessment
(Universidad de La SabanaMaestría en Didáctica del Inglés para el Aprendizaje Autodirigido (Virtual)Departamento de Lenguas y Culturas Extranjeras, 2019-10-30)
This action research project studies the effect of self-assessment strategies in first-semester university students’ segmental pronunciation while working in a Task-Based Language Teaching context. Ten students at a ...
Assessment of SAR speckle filters in the context of object-based image analysis
(Taylor & Francis, 2016-01)
The initial step in most object-based classification methodologies is the application of a segmentation algorithm to define objects. In the context of synthetic aperture radar (SAR) image analysis, the presence of speckle ...
Accuracy of connected confidence left ventricle segmentation in 3-D multi-slice computerized tomography images
(Institute of Electrical and Electronics Engineers Inc., 2018)
Cardiovascular diseases are the main cause of death in the World. This fact has motivated different actions for prevention, diagnosis and monitoring of cardiovascular diseases. In this work, the accuracy of a connected ...
Segmentation of colour food images using a robust algorithm
(ELSEVIER SCI LTD, 2005)
In this paper, a robust algorithm to segmenting food image from a background is presented using colour images. The proposed method has three steps: (i) computation of a high contrast grey value image from an optimal linear ...
Semiautomatic dental recognition using a graph-based segmentation algorithm and teeth shapes features
