  • Publication number: 20240135249
    Abstract: A learning device (10) according to the present disclosure includes a data set division unit (11) as a training data processing unit and a divided data set learning unit (12) as a model learning unit. The data set division unit (11) divides a new training data set into a plurality of divided data sets on the basis of attribute information. After performing model learning processing using an existing model as a learning target model, the divided data set learning unit (12) creates a new model by repeating the model learning processing until all the divided data sets are learned using a learned model created by the model learning processing as a new learning target model.

  • Patent number: 11516515
    Abstract: An image processing apparatus for performing correction for each frame group including a predetermined number of frames into which video data is divided includes a decoding unit configured to obtain a corrected frame group by correcting a second frame group, which is a frame group continuous with a first frame group in time, using a feature quantity of the first frame group. The decoding unit performs the correction so that subjective image quality based on a relationship between the second frame group and a frame group subsequent to the second frame group in time is increased and so that a predetermined classifier classifies that a frame group in which the second frame group is concatenated with the frame group subsequent to the second frame group in time is the same as a frame group in which the corrected frame group is concatenated with a corrected frame group obtained by correcting the frame group subsequent to the second frame group in time.

  • Publication number: 20220337830
    Abstract: A coding apparatus is a coding apparatus for coding an original image and includes: a division section that divides the original image into blocks that are a plurality of areas to acquire the plurality of blocks; a determination section that, for each of the blocks, determines whether or not to determine the block as an interpolation target; and a substitution section that substitutes a value of a pixel included in the block determined as the interpolation target, with a value that decreases a code amount of the block determined as the interpolation target. The determination section determines whether or not to determine the area that is a target of the determination as an area that is the interpolation target, using an evaluation based on an accuracy of prediction of an image of the block by intra prediction or inter prediction and a degree of the area that is the interpolation target being a generated one.

  • Publication number: 20220122297
    Abstract: A generation apparatus includes an interpolation unit that generates, from a moving image including a plurality of frames, an interpolated frame in which some regions in one or more frames included in the moving image are interpolated, and a discrimination unit that discriminates whether a plurality of input frames is interpolated frames in which some regions in the plurality of input frames is interpolated. The discrimination unit includes a temporal direction discrimination unit that discriminates time-wise the plurality of input frames, a spatial direction discrimination unit that discriminates space-wise the plurality of input frames, and an integrating unit that integrates discrimination results from the temporal direction discrimination unit and the spatial direction discrimination unit.

  • Publication number: 20220005233
    Abstract: An encoding apparatus encodes an input image and includes: a provisional encoded data acquisition unit configured to obtain provisional encoded data which has a size greater than a target size of encoded data which is data obtained by encoding the image based on the image and a parameter for determining the target size; and an encoded data acquisition unit configured to obtain the encoded data by converting data within a data range outside of a data range corresponding to the target size in the provisional encoded data into a predetermined value. The provisional encoded data acquisition unit obtains the provisional encoded data so that features for determining the image are contained more within the data range corresponding to the target size than in the data range outside of the data range corresponding to the target size.
