AI Technical Summary

Technical Problem

Existing methods for classifying facial acne suffer from insufficient granularity in lesion identification, poor consistency in assessments among different physicians, and a lack of objective quantitative indicators for treatment efficacy, resulting in imprecise, subjective, and unquantifiable assessments.

Method used

An intelligent grading method for facial acne based on image analysis is adopted, including standardized acquisition of facial images and skin color normalization preprocessing, localization of facial key points and resolution of regions of interest, segmentation and automatic counting of multiple types of acne lesions, region-weighted multi-feature fusion scoring, and image registration and efficacy quantitative evaluation before and after treatment, to construct a complete closed-loop solution.

Benefits of technology

It enables precise identification and automatic counting of skin lesion types such as acne, papules, pustules, nodules, and cysts, improving the clinical interpretability and consistency of the assessment results. It also provides an objective efficacy assessment by calculating the lesion clearance rate and the number of new lesions through image registration before and after treatment.

Abstract

The present application relates to the technical field of computer vision and medical image processing, and discloses a facial acne intelligent grading method and system based on image analysis, which comprises the following steps: facial image standardization acquisition and skin color normalization preprocessing, facial key point positioning and region of interest analysis, multi-type acne lesion instance segmentation and automatic counting, region weighted multi-feature fusion lesion severity comprehensive score, acne grade determination based on clinical grading standard, and image registration before and after treatment and curative effect quantitative evaluation. The present application eliminates the differences in illumination and skin color through skin color normalization, realizes fine identification of five types of skin lesions including comedones, papules, pustules, nodules and cysts, and outputs corresponding clinical grading results and curative effect evaluation report by combining region weight and category weight to calculate comprehensive score.
