Abstract: Disclosed herein are an X-ray imaging apparatus which recognizes a marker located at a part to be subjected to X-ray imaging from an image of a subject imaged by a camera and which controls a respective movement of each of an X-ray tube and an X-ray detector to a respective position which corresponds to the recognized marker, and a method for controlling the same. An X-ray imaging apparatus includes an X-ray tube which radiates X-rays toward a subject, an X-ray detector which detects X-rays which propagate through the subject, an imaging unit which generates an image of the subject, a recognizer which recognizes a part to be subjected to X-ray imaging from the image of the subject, and a position controller which controls a movement of the X-ray tube and the X-ray detector to a position corresponding to the part to be subjected to X-ray imaging.

Abstract: There is provide an image encoding method including transforming an image block into a first latent representation based on an invertible neural network, transforming the first latent representation into a second latent representation based on a non-invertible neural network, estimating a probability distribution of the first latent representation, and performing entropy encoding on the first latent representation based on the probability distribution by using an entropy encoder.

Abstract: An image encoding apparatus may include a memory storing one or more instructions; and a processor configured to execute the one or more instructions to: obtain an initial search position from a student neural network that has been trained through a knowledge distillation from a teacher neural network by inputting a current frame and a reference frame to the student neural network; and perform motion estimation based on the initial search position.
