Abstract
A method for generating an image of a dental arch of a beneficiary, called “modified image.” The method includes, at an acquisition time, acquiring a photo depicting the dental arch, called “original image.” The method successively includes processing the original image such that it depicts discriminating information. The method successively includes submitting the original image at the input of a neural network, called “simulation neural network”, trained, based on the original image, to simulate, on the original image, the effect of a dental event, in order to obtain the modified image.
Claims13
A non-transitory computer medium storing computer-program instructions for executing the steps of a method for generating an image of a dental arch of a beneficiary, called “modified image”, said method comprising the following successive steps:
- b) processing a photo depicting said dental arch such that it depicts discriminating information,
- said photo being called “original image” and being acquired at an acquisition time;
- c) submitting the original image at the input of a neural network, called “simulation neural network”, trained to proceed, from the original image, to a simulation on the original image, so that, at output of said simulation neural network, the obtained modified image depicts the dental arch after a dental event;
- wherein no three dimensional digital model is presented to the simulation neural network;
- wherein the simulation neural network is trained by way of a training method comprising, for each of a plurality of digital three-dimensional models of “historical” dental arches, called “historical models”, the following successive steps:
- 1) Acquiring a first view of the historical model under first observation conditions and, if said first view does not depict discriminating information of the historical dental arch, called “first discriminating information”, processing the first view such that it depicts said first discriminating information;
- 2) modifying the historical model, so as to reproduce the effect of said dental event on said historical dental arch;
- 3) acquiring a second view of the historical model under second observation conditions identical to the first observation conditions and, if said second view does not depict said discriminating information of the historical dental arch, called “second discriminating information”, processing the second view such that it depicts said second discriminating information;
- and then, with all of the first and second views acquired for all of the historical models:
- 4) Introducing said first and second views, respectively, at the input and at the output of the simulation neural network, so as to train said simulation neural network to transform an input view depicting an analysis dental arch into an output view depicting said analysis dental arch after application of said dental event.
