Embodiment Construction

[0031] Figure 8 It is a vectorized illustration of the range of inflammation and necrosis and the blank position of the present invention, and the color feature is extracted from the original picture. Through the observation of a large amount of data, it can be found that the color of pathological slices is mainly white and pink purple, and binarization can be used to extract the blank part. Therefore, in the process of color extraction, Gaussian blur is first performed on the original image to delete unnecessary details, and then the original image is binarized through an adaptive threshold algorithm to obtain the corresponding blank area.

[0032] Figure 9 is an example image of color feature extraction for original pathological slices of the present invention, such as Figure 9 As shown, after obtaining the prediction result of inflammation and necrosis range and the blank area after binarization, use the polygon tracking algorithm on the above picture to obtain the cor...

Abstract

The embodiment of the invention provides a medical image inflammation necrosis ratio calculation method and device, and the method comprises the steps: obtaining a pathological image; inputting the pathological image into a semantic segmentation model to obtain the category of each pixel point in the pathological image; determining an initial inflammation necrosis area according to the category of each pixel point; determining a background area and a blank area according to color features of the pathological image and the initial inflammation necrosis area; and determining an inflammation necrosis ratio according to the pathological image, the initial inflammation necrosis area, the background area and the blank area. According to the calculation method, the problem of mutual nesting between inflammation and necrosis is solved, the convergence difficulty is reduced, and the inflammation and necrosis ratio is quickly and accurately obtained.

Description

technical field [0001] The invention relates to the fields of medicine and image recognition, in particular to a method and device for calculating the proportion of inflammation and necrosis in medical images. Background technique [0002] In existing medical practice, medical personnel mainly judge the severity of a patient's disease by analyzing the coverage of inflammation and necrosis in pathological slides. Therefore, in medical clinical diagnosis, it is particularly important to quickly and accurately judge the proportion of inflammation and necrosis. The existing method mainly uses the traditional manual method to manually delineate the site of inflammation and necrosis and calculate the delineated range. This method is more efficient for cases with a small number of inflammation and necrosis, but for large-scale and complicated pathological slice images Said that the size of inflammation and necrosis is variable, and the types of inflammation and necrosis are nested...
