Abstract：To propose a novel automatic method to measure the fetal femur length.First, the candidate regions containing the femur were detected in the ultrasound image using maximum entropy segmentation and gray information.Then the femur region was localized based on both the shape and position of the candidate regions.Finally, the femur end points were detected by hypotenuse of enclosing rectangle of femur and the femur length was measured.Comparing with the results measured by doctors, the average error of 70 ultrasound femur images is 1.42±4.48 mm, which indicates our method can accurately measure the femur length.
