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...
Segmentation of ultrasound images is a challenging task due to the low signal-to-noise ratio of images, which is mainly caused by two factors: speckle noise and intensity inhomogeneities. A novel segmentation algorithm based on the fuzzy logic is proposed for simultaneously reducing speckle noise and compensating for intensity inhomogeneities. A two- dimensional fuzzy C-means (2DFCM) algorithm with...
