The rapid growth of image archives increases the need for efficient and fast tools that can retrieve and search through a large amount of visual data. In this paper, we propose an efficient method of extracting the image color content, which serves as an image digital signature, allowing us to efficiently index and retrieve the content of large,(More)
Calcification of vessels reduces their elasticity, affecting hemodynamic parameters of the cardiovascular system. The development of arterial hypertension, cardiac hypertrophy, ischemic heart disease or peripheral arterial disease significantly increases mortality in patients over 60 years of age. Stage of advancement and the extent of accumulation of(More)
A new filtering approach designed to eliminate impulsive noise in color images, while preserving fine image details is presented in this paper. The computational complexity of the new filter is significantly lower than that of the Vector Median Filter. The comparison shows that the new filter outperforms the VMF, as well as other standard procedures used in(More)

OBJECTIVE The objective of this study was to identify predictors of long-term weight loss after inpatient psychodynamic or behavioral psychotherapy of severely obese patients. METHODS In a longitudinal study, obese patients [body mass index (BMI)>or=35 kg/m(2)] were randomly assigned to behavioral or psychodynamic inpatient treatment. The average(More)
