Title:
METHOD EMPLOYING ARTIFICIAL NEURAL NETWORK TO ELIMINATE SURFACE BUBBLES FROM THREE-DIMENSIONAL DIGITAL MODEL OF TOOTH
Document Type and Number:
WIPO Patent Application WO/2020/181974
Kind Code:
A1
Abstract:
In one aspect of the present invention, a method employing an artificial neural network to eliminate surface bubbles from a three-dimensional digital model of a tooth and executable by a computer is provided. The method comprises: acquiring a three-dimensional digital model of a first tooth; extracting features from the three-dimensional digital model of the first tooth; using a trained artificial neural network to recognize surface bubbles in the three-dimensional digital model of the first tooth on the basis of the extracted features; and eliminating the recognized surface bubbles.
