This subjects the patients to excess radiation exposure and extra cost.It is therefore investigating the magnitude and causes of reject is mandatory. This study aimed to assess the reject rate of X-ray films and its economic implication in order to obtain...

In this paper a method defining a reject option applicable to a given 0-reject classifier is proposed. The reject option is based on an estimate of the classification reliability, measured by a reliability evaluator . Trivially, once a reject threshold has been fixed, a sample is rejected if the corresponding value of is below . Obviously, as represents the least tolerable classification reliab...
