Abstract

Recognition of landmarks represents a difficult problem in the field of spine kinematics. Automatic software for the selection of the position of vertebrae in a sequence of videofluoroscopic images has been developed as a means removing the need for manual making of bony landmarks. Lumbar coronal and sagittal images are sequentially grabbed from a videofluoroscopic device. Videofluoroscopy produces dynamic x-ray images using low radiation exposure but results in relatively poor images. Due to this poor quality and the absence of reference points, a method of statistical recognition based upon recursive cross- correlation has been developed to track th
