The invention discloses a melanoma segmentation method, device and related components of a dermoscopic image. The method includes extracting features from dermoscopic sample images through the pre-trained Res2Net model to generate low-level features and high-level features; performing cross-layer feature fusion on low-level features and high-level features to obtain a global map; Convolve the features, and use the global map to guide the intermediate prediction map obtained by convolution to obtain the final prediction map; use the loss function to supervise and optimize the final prediction map, intermediate prediction map and global map at the same time, and get the optimized The dermoscopic image melanoma segmentation model is used; the dermoscopic detection image is segmented using the dermoscopic image melanoma segmentation model, and the segmentation results are output. This method can quickly and effectively segment the melanoma region in the dermoscopic image, and the output segmentation results have accurate boundaries.
Description
technical field [0001] The invention relates to the field of computer-aided medicine, in particular to a melanoma segmentation method, device and related components of a dermoscopic image. Background technique [0002] Malignant melanoma is not obvious in the early stage, and it is difficult for experienced clinicians to predict directly with the naked eye, but dermoscopy is the best way to check melanoma, and dermoscopy imaging technology has become the first choice for malignant melanoma. Effective tool for clinical diagnosis. [0003] Dermoscopy, also known as epidermal light transmission microscope, skin surface microscope, incident light microscope, etc., is a non-invasive skin microscopic image analysis technology, using oil immersion, light and optical magnification equipment, can observe including the lower part of the epidermis It is an effective tool for diagnosing melanoma and other colored skin lesions mainly by detecting skin structures invisible to the naked e...
