Auto-Detection of Femur Length Using Ultrasound Image Processing Techniques

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.
