摘要： A forming method of a synthetic discriminant function for use in discriminating characters when each of the character is correlatively calculated with a character pattern. The synthetic discriminant function is formed in the manner that a Fischer ratio shown by the below equation is applied to a criterion for evaluation;
in which y 1 , y 2 represent the expectation value of correlation output value of each class when the character patterns are discriminated into two classes by the synthetic discriminant function, and 01 represents the variance of correlation output value.

摘要： A system for screening luggage items, which includes an image generation device suitable for generating an image signal associated with a luggage item where the image signal conveys information related to the contents of the luggage item. The system also includes an apparatus having an input for receiving the image signal and a processing unit. The processing unit processes the image signal in combination with a plurality of target images associated with target objects to detect a presence of at least one target object in the luggage item. The processing unit generates a detection signal in response to detection of the presence of at least one target object in the luggage item. An output module conveys information derived at least in part on the basis of the detection signal to a user of the system. In alternative embodiments, the system may also be used to screen cargo containers and persons.
