Skin cancer, specifically melanoma, is a serious health issue that arises from the melanocytes, the cells that produce melanin, the pigment responsible for skin color. With skin cancer on the rise, the timely identification of skin lesions is crucial for effective treatment. However, the similarity between some skin lesions can result in misclassification, which is a significant problem. It is important to note that benign skin lesions are more prevalent than malignant ones, which can lead to overly cautious algorithms and incorrect results. As a solution, researchers are developing computer-assisted diagnostic tools to detect malignant tumors early. First, a new model based on the combination of "you only look once" (YOLOv5) and "ResNet50" is proposed for melanoma detection with its degree using humans against a machine with 10,000 training images (HAM10000). Second, feature maps integrate gradient change, which allows rapid inference, boosts precision, and reduces the number of hyperparameters in the model, making it smaller. Finally, the current YOLOv5 model is changed to obtain the desired outcomes by adding new classes for dermatoscopic images of typical lesions with pigmented skin. The proposed approach improves melanoma detection with a real-time speed of 0.4 MS of non-maximum suppression (NMS) per image. The performance metrics average is 99.0%, 98.6%, 98.8%, 99.5, 98.3%, and 98.7% for the precision, recall, dice similarity coefficient (DSC), accuracy, mean average precision (MAP) from 0.0 to 0.5, and MAP from 0.5 to 0.95, respectively. Compared to current melanoma detection approaches, the provided approach is more efficient in using deep features.
皮肤癌,尤其是黑色素瘤,是一个严重的健康问题,它起源于黑素细胞,即产生黑色素(负责皮肤颜色的色素)的细胞。随着皮肤癌发病率的上升,及时识别皮肤病变对于有效治疗至关重要。然而,一些皮肤病变之间的相似性可能导致错误分类,这是一个重大问题。需要注意的是,良性皮肤病变比恶性病变更为普遍,这可能导致算法过于谨慎并产生错误结果。作为一种解决方案,研究人员正在开发计算机辅助诊断工具以早期检测恶性肿瘤。首先,提出了一种基于“你只看一次”(YOLOv5)和“ResNet50”相结合的新模型,用于使用10000张训练图像(HAM10000)对黑色素瘤进行检测并评估其程度,同时以人工与机器进行对比。其次,特征图整合了梯度变化,这使得推理速度加快、精度提高,并减少了模型中的超参数数量,从而使模型更小。最后,通过为典型色素沉着皮肤病变的皮肤镜图像添加新类别来改变当前的YOLOv5模型,以获得理想的结果。所提出的方法以每张图像0.4毫秒的非极大值抑制(NMS)实时速度提高了黑色素瘤检测的性能。对于精度、召回率、骰子相似系数(DSC)、准确率、0至0.5的平均精度均值(MAP)以及0.5至0.95的MAP,性能指标平均值分别为99.0%、98.6%、98.8%、99.5%、98.3%和98.7%。与当前的黑色素瘤检测方法相比,所提供的方法在使用深度特征方面更有效。
