  • Patent number: 11165948
    Abstract: An imaging apparatus configured to estimate information about an imaging setting of the imaging apparatus by using a trained model. The imaging apparatus includes a detection unit configured to detect a first operation for finalizing imaging and a second operation for interrupting imaging of the imaging apparatus in which the imaging setting has been made based on the information estimated by the trained model, and a training unit configured to update a connection weight of the trained model through reinforcement learning by determining, when the first operation is detected by the detection unit, a positive reward, and when the second operation is detected by the detection unit, a negative reward for the information having been estimated when the first or second operation is detected by the detection unit.

  • Patent number: 10216979
    Abstract: An image processing apparatus includes an acquisition unit, a first detection unit, a selection unit, and a correction unit. The acquisition unit acquires an image including a target object having a plurality of parts. The first detection unit detects a candidate region of each of the plurality of parts of the target object included in the acquired image using a previously learned model. The selection unit selects, based on the candidate region detected by the first detection unit, a first part having relatively high reliability and a second part having relatively low reliability from among the plurality of parts. The correction unit corrects the model by changing a position of the second part based on the first part selected by the selection unit.

  • Patent number: 9665803
    Abstract: A dictionary for detection of an object is created from an image obtained by performing an image process, which depends on a first image process parameter, on the training image of the detection target object. The dictionary created based on the image process depending on the first image process parameter is determined, based on a result of detecting the object from an image obtained by performing an image process, which depends on the first image process parameter, on a photographed image based on the dictionary. A second image process parameter is determined, based on a result of detecting the object from an image obtained by performing an image process, which depends on the second image process parameter, on the photographed image using the determined dictionary.
