Article
Comparing Different Classifiers for Automatic Age Estimation
(2004)We describe a quantitative evaluation of the performance of different classifiers in the task of automatic age estimation. In this context, we generate a statistical model of facial appearance, which is subsequently used ...

Article
Computer-aided diagnosis in hysteroscopic imaging
(2015)The paper presents the development of a computeraided diagnostic (CAD) system for the early detection of endometrial cancer. The proposed CAD system supports reproducibility through texture feature standardization, ...

Article
Effect of zooming on texture features of ultrasonic images
(2006)Background: Unstable carotid plaques on subjective, visual, assessment using B-mode ultrasound scanning appear as echolucent and heterogeneous. Although previous studies on computer assisted plaque characterisation have ...

Article
An integrated system for the segmentation of atherosclerotic carotid plaque ultrasound video
(2014)The robust border identification of atherosclerotic carotid plaque, the corresponding degree of stenosis of the common carotid artery (CCA), and also the characteristics of the arterial wall, including plaque size, ...

Ultrasound image texture analysis of the intima and media layers of the common carotid artery and its correlation with age and gender
(2009)The intima-media thickness (IMT) of the common carotid artery (CCA) is widely used as an early indicator of cardiovascular disease (CVD). It was proposed but not thoroughly investigated that the composition and texture of ...
