Image processing technologies may be employed for quicker and accurate diagnosis in analysis feature extraction of medical images. Here, existing level set algorithm is modified it extracting contour fetus an image. In traditional approach, fetal parameters are extracted manually from ultrasound An automatic technique highly desirable to obtain biometric measurements due some problems approach ...

In this paper we describe a new approach to contour extraction and tracking, which is based on the principles of active contour models and overcomes its shortcomings. We formally introduce active rays, describe the contour extraction as an energy minimization problem and discuss what active contours and active rays have in common. The main diierence is that for active rays a unique ordering of ...
