Embodiment Construction

[0061] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0062] like figure 1 As shown, a correlation-based evaluation method for the therapeutic effect of hypertrophic scars includes the following steps:

[0063] 1) Obtain hypertrophic scar images before treatment, hypertrophic scar images after treatment with carbon dioxide fractional laser, and corresponding normal skin images of adjacent scars before and after treatment;

[0064] 2) Using the energy watershed segmentation algorithm to obtain the scar regions of the scar images before and after treatment;

[0065] 3) Obtain the correlation vector MI between the scar area and the corres...

Abstract

The invention relates to a method and system for evaluating a hypertrophic scar treatment effect based on correlation. The method comprises the following steps: 1) respectively obtaining a scar image before treatment, a scar image after treatment and a corresponding normal skin image adjacent to a scar before and after the treatment; 2) obtaining scar areas of the scar image before treatment and the scar image after treatment; 3) obtaining correlation vectors MIj, n and MIk, m; and 4) performing statistical analysis, separately calculating a mean, a standard difference and a significant difference P value of the correlation vectors MIj, n and MIk, m, and performing analysis to obtain a treatment effect evaluation result according to a calculation result. Compared with the prior art, by adoption of the method and system provided by the invention, micro changes cannot be recognized by eyes can be identified, compared with naked eye evaluation of experts and Vancouver scar scale evaluation, the evaluation method is more objective, the problem of low reliability between evaluation scale observers is avoided, the user acceptance is good, and the method and system has the advantages of reliable evaluation result, strong repeatability and practicability, etc.

Description

technical field [0001] The invention relates to a method for evaluating the therapeutic effect of hypertrophic scars, in particular to a method and system for evaluating the therapeutic effects of hypertrophic scars based on correlation. Background technique [0002] The evaluation of scar treatment effect is a hot issue in clinical medicine. Accurate clinical evaluation of scar treatment effect will help doctors choose the correct treatment method at each stage, which is of great significance to the clinical treatment and research of scar diseases. [0003] Scar assessment is mainly divided into scar assessment scale and scar assessment tool. The scar evaluation scale mainly evaluates scars from five aspects: color, thickness, surface characteristics, softness and surface area. Common scar scales are: Vancouver Scar Scale, Seattle Scar Scale, Stonebrook Scar Scale, Manchester Scar Scale, Patient and Observer Scar Scale. The Vancouver Scar Scale is the most widely used eva...
