Detection system, detection apparatus, learning apparatus, detection method, learning method and program

A detection system comprising a learning apparatus and a detection apparatus, wherein:

• the learning apparatus comprises
• a first preprocessing unit that extracts, from a captured image used for training, which includes a noise image and an image of an object having a detection target, a training image including an image of the detection target, based on a structure around the detection target, and
• a training unit that trains a machine learning model based on the training image;
• and
• the detection apparatus comprises
• an acquisition unit that acquires the machine learning model,
• a second preprocessing unit that extracts, from a captured image used for detection, which includes the noise image and the image of the object having the detection target, candidates for being the detection target image in which the detection target is captured, based on the structure around the detection target, and
• a detection unit that detects, in the captured image used for detection, the detection target image from among the detection target image candidates, by using the machine learning model.
