摘要： A method of detecting a radiographic object is proposed. The method includes receiving, by a feature processing module, an input of radiographic image obtained by irradiating a region containing a plurality of tubes including at least one target tube as a radiographic object and at least one untargeted tube that is not a radiographic object, extracting, by the feature processing module, feature values of extremal points from the radiographic image to detect feature vectors, and analyzing, by a detection module, the feature vectors using a training model to detect a region in the radiographic image where the at least one target tube as a radiographic object exists.
