  • Publication number: 20240282077
    Abstract: An image processing apparatus includes a feature extractor, a map estimator, a first image estimator, a second image estimator, and an outputter. The feature extractor extracts an intermediate feature from an input image. The map estimator estimates an area map from the intermediate feature. The first image estimator estimates a first image from the intermediate feature. The second image estimator estimates a second image from the intermediate feature. The outputter outputs an output image obtained by, based on the area map, merging the first image and the second image. The second image estimator is trained to obtain desired image quality at a particular area based on the area map in the second image.

  • Publication number: 20230073357
    Abstract: There is provided with an information processing apparatus including a machine learning model configured to perform a recognition process on a recognition target in a captured image, based on pixel information of the captured image, and information about the captured image in addition to the pixel information. An inputting unit inputs the pixel information to a first portion of the machine learning model. A processing unit performs the recognition process by inputting correction information obtained by correcting an output of the first portion of the machine learning model by using the information about the captured image, to a second portion of the machine learning model, which follows the first portion.

  • Publication number: 20220366242
    Abstract: An information processing apparatus is operable to train a machine learning model that has a hierarchical structure configured by a plurality of hierarchical layers and that is used for recognizing a recognition target in inputted data. An obtaining unit obtains input data and data indicating a ground truth of an output from the machine learning model regarding the input data. A learning unit trains the machine learning model based on an error between the data indicating the ground truth of the output from the machine learning model regarding a specific domain of the input data and at least one output in an intermediate layer of the machine learning model with respect to the input data.
