The invention discloses a
human body hidden thing
image segmentation method based on an X-
ray back scattering image. The method comprises the steps of collecting the X-
ray back scattering image, preprocessing the X-
ray back scattering image, obtaining an image after preprocessing, carrying out statistics on the preprocessed image, extracting
human body areas, gaining the average grey degree u0 of the
human body areas, classifying the human body areas again through a K-mean
algorithm and a Bayesian classification
algorithm and extracting human body hidden things by using a zone marker method. According to the human body hidden thing
image segmentation method based on the X-ray back scattering image, the data size is reduced to the greatest extent under the condition that an effect can not be affected, so that computing time is shortened, and the purpose of real-time performance is achieved. Objects which have the relatively
low contrast ratio with the background can be well detected. Through two-time segmentation, the purposes that the objects and the background are distinguished and the hidden things are well detected are achieved by using the middle background of a human body, the hidden things are automatically marked, and manual marking is avoided.
