يقدم البحث طريقة مبتكرة لقياس طول عظم فخذ الجنين في الصور فوق الصوتية, حيث
يقوم بتقليل كمية الضجيج الموجودة في تلك الصور, و من ثم تحويلها إلى الشكل الثنائي
و اجراء عمليات مورفولوجية لتجزئة عظم الفخذ و عزله عن باقي عناصر الصورة, ثم
يستخدم كاشف حواف من أجل إيجاد حواف العظم, و يطبق بعد ذلك تحويل هوف لكشف
الخطوط المستقيمة في الصورة, ليقوم بمراكبة المستقيمات الناتجة على الصورة الأصلية,
و المستقيم الأبرز و الأطول هو المستقيم المقابل لعظم الفخذ, و يتم حساب طوله
بالميلليمتر.
This Paper offers an effective method to measure the length of the
femur in Fetal Ultrasound Images, it applies a series of steps
starting with the reducing amount of noise in these images, and
then converted them to a binary form and uses morphological
operations to segment the femur and isolate it from the rest of the
image objects, then it applies an Edge Detector in order to find the
edges of the bone, then uses the Hough Transform to detect straight
lines in the image. we apply overlapping for resulted lines on the
original image, finally we choose the most significant and longest
straight line which is corresponding to the length of the femur. The
proposed method facilitates the measurement of the femur without
the help of a physician through a series of steps.

ultrasound US images. There is high amount of noise in US images, which it affects the
visual appearance of the area of head. The research depends on auto segmentation
