Claim:
1. A method for an automated detection of swallowed capsules on X-ray scanner images, the method comprising: (a) acquiring an incoming image of a person passing through the scanner; (b) generating additional images based on the incoming image by performing transformations of the incoming image; (c) determining an upper body area on the incoming image; (d) calculating a position of a stomach area on the upper body area of the incoming image and on the additional images; (e) classifying segmented regions of the stomach area of the incoming image; (f) calculating geometrical and intensity features along with rotationally invariant periodic features for windows on the stomach area; (g) detecting suspected windows on the stomach area; (h) calculating aggregate features for the properties of the suspected windows; (i) using a model for the images that do not contain swallowed capsules classifying the incoming image using a threshold for a dissimilarity function; and (j) informing a user that the incoming image contains the swallowed capsules if the dissimilarity function for aggregate features for the incoming image is larger than or equal to the threshold.
