Abstract: A data creation system creates, based on first image data, second image data for use as learning data to generate a learned model about an object. The data creation system includes a deformer that generates, based on the first image data including a pixel region representing the object, the second image data by deforming a shape of the object. The deformer generates the second image data to maintain a predetermined feature of the first image data before and after the shape of the object is deformed.

Abstract: A method and system for sampling and augmenting a dataset associated with a first class and a second class, respectively, to balance the dataset of images is described. The method includes receiving a required number of reduced set of dataset images associated with the first class, creating a plurality of clusters from a set of images associated with the first class, and selecting a representative image from each cluster to provide a reduced set of images. Further, a median image and a non-defect artifact mask is generated corresponding to the set of images associated with the first class. Additionally, a defect foreground is extracted based on the median image and each defect image of another set of images associated with the second class. Finally, the at least one non-defect artifact is removed from the defect foreground to provide a new synthetic defect image for each defect image for augmentation.

Abstract: A data creation system creates, based on first image data, second image data for use as learning data to generate a learned model about an object. The data creation system includes a deformer, a remover, a feature acquirer, and a feature assigner. The deformer generates, based on the first image data including a pixel region representing the object, the second image data by causing deformation about the object to the first image data. The remover removes a linear first feature present in the first image data. The feature acquirer acquires a second feature. The feature assigner assigns the second feature to the second image data.

Abstract: A data creation system creates, based on first image data, second image data for use as learning data to generate a learned model. The data creation system includes an acquirer and a superimposer. The acquirer acquires feature image data indicating respective pixel values of a plurality of pixels included in a feature region. The superimposer creates the second image data by superimposing a magnitude of shift on respective pixel values of a plurality of pixels included in a predetermined region of a first image represented by the first image data. The predetermined region has an outer peripheral shape corresponding to the feature region. The magnitude of shift is determined based on the respective pixel values of the plurality of pixels included in the feature region.

Abstract: A data creation system creates, based on first image data, second image data for use as learning data. A processor of the data creation system generates, based on the first image data including a first region as a pixel region representing the object and a second region adjacent to the first region, the second image data by causing deformation about height of the first region with respect to a reference plane. The processor generates the second image data such that the closer to a reference point within the first region a point of interest is, the greater a variation in the height of the first region with respect to the reference plane is and the closer to a boundary between the first region and the second region the point of interest is, the smaller the variation in the height of the first region with respect to the reference plane is.
