Embodiment

[0038] Such as figure 1 As shown, a method for evaluating the effect of scar treatment based on image processing mainly includes an image preprocessing stage, an image registration stage, and a mutual information calculation stage. Specifically, the method includes the following steps:

[0039] Execute Step 1: Obtain the scar image before treatment, the scar image after treatment, and the normal skin image of the adjacent scar before treatment. In this embodiment, a high-definition camera is used to capture the above three pictures, and Step 2 is performed.

[0040] Execute step 2: preprocess the acquired images respectively to obtain scar RGB images before treatment, scar RGB images after treatment and normal skin RGB images, and perform step 3.

[0041] Specifically step 2 includes the following sub-steps:

[0042] (2a) Image conversion: convert the scar image before treatment, the scar image after treatment and the normal skin image into RGB images;

[0043] (2b) image en...

Abstract

The invention relates to an image-processing-based evaluation method for a scar treatment effect. The method comprises: (1), a scar image before treatment, a scar image after treatment, and a image of an abnormal skin adjacent to the mark before treatment of a patient are obtained; (2), pretreatment is carried out on the obtained images respectively to obtain a scar RGB image before treatment, a scar RGB image after treatment, and a normal skin RGB image; (3), the scar RGB image before treatment and the scar RGB image after treatment after the pretreatment are registered to obtain a registered scar RGB image after treatment; (4), calculation is carried out to obtain that mutual information between the scar RGB image before treatment and the normal skin RGB image is I(A,B) and that mutual information between the registered scar RGB image after treatment and the normal skin RGB image is I (C,B); and (5), whether the I (C,B) is larger than I(A,B) is determined; if so, the treatment effect is good; and otherwise, the treatment effect is poor. Compared with the prior art, the method has advantages of reliable evaluation result, high repeatability, and high practicability and the like.

Description

technical field [0001] The invention relates to an evaluation method of scar treatment effect, in particular to an image processing-based evaluation method of scar treatment effect. 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 evaluation scale clinically. Observers give evaluation scor...
