Abstract: A display apparatus and an operating method thereof obtain at least one first sensor data of a first point in time, receive a first image frame including a first augmented reality (AR) object corresponding to the first point in time, the first AR object generated by a first processor, based on the first sensor data, obtain second sensor data of a second point in time subsequent to the first point in time, correct the first AR object to a second AR object matched to the second point in time, based on the second sensor data, and display a second image frame including the second AR object.

Abstract: A processor-implemented learning method for an image segmentation includes training first duplicate layers, as duplications of trained first layers of a pre-trained model, so that a second feature extracted from a target image by the trained first duplicate layers is matched to a first feature extracted from a training image by the trained first layers; regularizing the trained first duplicate layers so that a similarity between the first feature and a third feature extracted from the training image by the regularized first duplicate layers meets a threshold; and training second duplicate layers, as duplications of trained second layers of the pre-trained model, to be configured to segment the target image based on the regularized first duplicate layers, the trained second layer being configured to segment the training image.

Abstract: A method of displaying caustics, the method includes determining intersection positions at which rays emitted from a light source pass through particles of a first object and meet a second object; applying caustic textures to the intersection positions; and rendering the first object using a caustic map based on a result of the applying caustic textures to the intersection positions.

Abstract: An image processing apparatus includes a memory configured to store a data structure in which gather rays generated by performing gather ray tracing from a rendering viewpoint are clustered hierarchically, the gather rays including a first gather ray and a second gather ray associated with the first gather ray in the data structure, and a processor configured to merge a photon gathering result associated with the second gather ray with a photon gathering result associated with the first gather ray in response to the photon gathering result associated with the first gather ray not satisfying a first condition.
