متن کاملColor to Grayscale Conversion with Chrominance Contrast
Color information is usually discarded when converting a color image into a grayscale image. However, it is sometimes desirable to reflect chrominance change where luminance contrast is not obvious. Inspired by tone mapping technique, this paper proposes a similar method for color to grayscale conversion, which in addition takes into account the local chrominance changes. The result shows great...
متن کاملDifferentiation of benign and malignant superficial soft-tissue masses using grayscale and color doppler ultrasonography.
BACKGROUND This study was performed to evaluate the usefulness of high-resolution grayscale and color Doppler ultrasound to distinguish benign from malignant soft-tissue masses on the basis of ultrasonographic patterns. METHODS We enrolled 398 female and 420 male patients aged 1-104 years (mean, 49.8 years). All presented with a palpable nodule or mass located superficially in the body. Each ...
متن کاملReliable Parameters of Color Doppler Ultrasonography for Predicting Thyroid Function
To compare and determine color Doppler ultrasonography (CDU) parameters that is the most reliable parameter for predicting thyroid functional status between euthyroid and hyperthyroid states. We retrospectively reviewed data from a total of 256 patients (197 females and 59 males) who had undergone CDU from December 2003 to April 2008. Patients’ age ranged from 11-81 yr with average of 38.6 yr. ...
