The invention provides a mammary gland image enhancement method, and the method comprises the steps: carrying out the normalization of the pixel value of an original mammary gland image, and obtaininga first image; adopting gaussian-logarithm transformation to perform transformation stretching on the first image, so as to obtain a second image; calculating a contrast normalization factor according to the second image and carrying out Laplace image decomposition to obtain a third image after contrast normalization; and performing enhancement processing and Laplace image reconstruction on the third image to obtain an enhanced fourth image, and performing gradual change processing on the fourth image by using a gradual change curve suitable for display to obtain a target mammary gland image.The problem of poor visibility of subcutaneous tissues and skin lines caused by image overexposure can be effectively solved, the problem of inconsistent brightness and contrast after image enhancement is effectively solved, the layering sense among different tissues in the image is effectively improved, and the method is conveniently applied to clinical diagnosis.
Description
technical field [0001] The embodiments of the present application relate to the technical field of image enhancement, and in particular to a breast image enhancement method, device, and computer-readable storage medium. Background technique [0002] Breast images have high spatial resolution and wide dynamic range. Image enhancement processing can extract rich clinical diagnostic information and provide a good diagnostic basis for the diagnosis of breast diseases, especially the discovery of early lesions. Because the lesion information such as details in the original breast image is concentrated in a narrow gray range, but its useful gray range is widely distributed, it is difficult for the human eye to distinguish diagnostic information from it. Therefore, the original breast images need to be processed with detail enhancement to obtain diagnosable clinical images. [0003] Unsharp masks were one of the earliest methods used for image enhancement. In this method, the ori...
