Estimation of age from image processing of soft X-ray findings in Japanese male thyroid cartilages.
A method was developed for estimating the age at death based on image processing of soft X-ray pictures of thyroid cartilage from Japanese males. Data for 501 individuals were used to derive equations for this determination. Prior to image processing, gross morphological findings were used for estimation. Soft X-ray pictures indicated ossification with age and one index for image processing was introduced. The exponential function was applied to age estimation.
