Facial Landmark Angle Measurement for Jawline Treatment Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is difficult for users to objectively assess the effectiveness of anti-aging products and treatments on their skin, particularly in terms of reducing signs of aging such as flattening of cheeks, sagging jawlines, and loss of definition, making it challenging to modify regimens or products for optimal results.
Innovation Solution
A method is developed to measure the angle between the x-axis and a facial landmark line on the jawline before and after treatment, using a coordinate system defined by the center of the chin, to objectively evaluate the effectiveness of anti-aging treatments, allowing for modifications based on the angle changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If various anti-aging products are used to firm skin and modify signs of aging, then the aesthetic appearance of the face is improved, but the effectiveness of these products is difficult to objectively assess
Solution Approach 1:
The patent applies image processing techniques to detect and measure changes in facial landmark positions and jawline angles from photographs. By converting visual information into quantifiable angular measurements, the system provides objective assessment of treatment effectiveness, resolving the contradiction between improving aesthetic appearance and enabling precise measurement of results.
2Reliability
If subjective assessment methods are used to evaluate treatment effectiveness, then the assessment process is simple, but the reliability and objectivity of the results are poor
Solution Approach 1:
The patent replaces subjective human assessment with an automated image processing system that uses computer vision algorithms to detect facial landmarks and calculate jawline angles. This substitution of mechanical/automated systems for human judgment provides reliable, objective measurements while maintaining ease of use through simple photograph capture and automated analysis.
3Adaptability or versatility
If no objective measurement method is provided, then the treatment regimen can be freely modified, but the user cannot know whether modifications are improving results
Solution Approach 1:
The patent implements a feedback mechanism by comparing jawline angles measured before and after treatment, providing users with quantitative information about treatment effectiveness. This feedback enables informed decisions about whether to continue, modify, or discontinue treatment regimens, resolving the contradiction between adaptability and information loss by providing the necessary effectiveness data to guide modifications.

AI summary
Provided are methods of determining effectiveness of face treatments comprising: providing a front-facing image of the face prior to use of the treatment; identifying a y-axis of the face, wherein the y-axis is defined by a line connecting the center position of the chin of the face through the center of the face; identifying an x-axis of the face, wherein the x-axis is defined by a line that is positioned at a 90-degree angle from the y-axis and goes through the center of the chin of the face; selecting a facial landmark; identifying a facial landmark line, wherein the facial landmark line is defined by a line connecting the center position of the chin of the face to the facial landmark; measuring the angle between the x-axis and the facial landmark line; carrying out the treatment on the face; providing a front-facing image of the face after the treatment.
