Combined with human visual characteristics and morphological watershed algorithm, a novel image processing method was proposed for automatic region of interest (ROI) extraction. The color image would be converted into gradient map, then smooth the map using the method of morphological opening and closing operators, last thresholding it. For discriminating the very small regions which are segmented...
Parameters of the fetal nuchal translucency (NT) are very important for the diagnosis and evaluation of fetuses. Currently these parameters are manually measured from the fetal ultrasound image, which may introduce problems of the variability and reproducibility. Here an automatic scheme is proposed to estimate fetal NT parameters. With a morphologic filtering, this scheme firstly establishes the...
