Systems and methods for teeth whitening simulation

A method of creating an image corresponding to a dental whitening treatment, the method comprising:

• receiving a two-dimensional (2D) image of a patient's teeth;
• identifying individual teeth within the 2D image of the patient's teeth;
• converting the 2D image from a native color space into a CIELAB color space;
• selecting a change in a blue-yellow color value (delta b value) with which to whiten the patient's teeth, wherein the delta b value is selected to increase a blue hue and decrease a yellow hue;
• identify a maximum lightness value from the patient's teeth;
• transforming the 2D image in the CIELAB color space by adjusting delta b values of each tooth by a modified version of the delta b value that is scaled for each tooth based on a ratio of a lightness value of each tooth relative to the maximum lightness value to form a whitened 2D image, wherein adjusting the delta b values comprises limiting the delta b values to within a predetermined range;
• and
• outputting the whitened 2D image.

A system for simulating a teeth whitening procedure, the system comprising:

• one or more processors;
• and
• a memory configured to store instructions that, when executed by the one or more processors, cause the system to:
• receive a two-dimensional (2D) image of a patient's teeth;
• identify individual teeth within the 2D image of the patient's teeth;
• convert the 2D image from a native color space into a CIELAB color space;
• select a change in a blue-yellow color value (delta b value) with which to whiten the patient's teeth, wherein the delta b value is selected to increase a blue hue and decrease a yellow hue;
• identify a maximum lightness value from the patient's teeth;
• transform the 2D image in the CIELAB color space by adjusting delta b values of each tooth by a modified version of the delta b value that is scaled for each tooth based on a ratio of a lightness value of each tooth relative to the maximum lightness value to form a whitened 2D image, wherein adjusting the delta b values comprises limiting the delta b values to within a predetermined range;
• and
• output the whitened 2D image.
