  • Publication number: 20200175377
    Abstract: There is provided with a training apparatus for training a neural network. The neural network, when an input image is inputted, outputs a detection result of a first type and a detection result of a second type for each position of the input image. A training data obtaining unit obtains a training image to be input to the neural network for training. An error map obtaining unit obtains an error map indicating a detection error for a detection result of the first type, for each position of the training image. A training unit trains the neural network using the detection result of the first type and the detection result of the second type that are obtained by inputting the training image to the neural network, and the error map.

  • 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.
