Abstract: A method for registering a tooth image with a tooth structure according to an embodiment includes a first registering step for registering a tooth image model obtained from a medical image taken when an object bites a bite including a marker with a bite scanning model obtained by scanning the bite, a second registering step for registering the bite scanning model with a tooth scanning model obtained by scanning a tooth shape of the object, and a third registering step for registering the tooth image model with the tooth scanning model based on the results of the first registering step and the results of the second registering step. As a result, a model including an accurate shape of tooth part difficult to obtain from a medical imaging apparatus can be easily obtained.

Abstract: Disclosed herein is an image preprocessing/analysis apparatus using machine learning-based artificial intelligence. The image preprocessing apparatus includes a computing system, and the computing system includes: a processor; a communication interface configured to receive an input image; and an artificial neural network configured to generate first and second preprocessing conditions through inference on the input image. The processor includes a first preprocessing module configured to generate a first preprocessed image and a second preprocessing module configured to generate a second preprocessed image. The processor is configured to control the first preprocessing module, the second preprocessing module, the artificial neural network, and the communication interface so that the first preprocessed image and the second preprocessed image are transferred to an image analysis module configured to perform image analysis on the input image based on the first preprocessed image and the second preprocessed image.
