In order to solve the problem of low efficiency and accuracy of injury image recognition for sports athletes in high-intensity injury treatment, this paper proposes an injury recognition mode based on the deep neural network. In this paper, the image of sports injury is converted to gray level, and the contour of the injury part in the image is extracted according to the combination of adaptive thresholding and mathematical morphology. In this model, the seed points are selected, the active contour is used to approximate the initial contour, and the curve fitting method is used to fit the obtained discrete points to obtain the final damaged contour. The digital matrix is constructed by using the extracted number of pixels at the damaged position and relevant information. The images are arranged into feature vectors with a length of 64 according to the mode of column concatenation. The overall mean vector of the image is calculated. The calculation results, training samples, and image samples to be recognized are substituted into the Euclidean distance to obtain the preliminary recognition results of the damaged position of the image of sports injury. Then, the image segmentation is realized by clustering. The clustering segmentation results are used to color describe the pixel categories of the original image, calculate the relative damage proportion area in the sports injury image, and identify the damage parts of the high-intensity sports injury image. The experimental results show that the recognition rate of the neural network is 80%-100%, and the recognition time of this method is 0-0.6/s. The above method can improve the accuracy of the recognition of the damaged part of the sports injury image and shorten the recognition time and has certain feasibility in determining the sports injury part.
为了解决高强度运动损伤治疗中运动员损伤图像识别效率和准确率低的问题,本文提出了一种基于深度神经网络的损伤识别模式。在本文中,将运动损伤图像转换为灰度图像,并根据自适应阈值和数学形态学的组合提取图像中损伤部位的轮廓。在该模型中,选择种子点,使用主动轮廓逼近初始轮廓,使用曲线拟合方法拟合得到的离散点,得到最终的损伤轮廓。通过使用提取的损伤位置的像素数和相关信息构建数字矩阵。将图像排列成长度为 64 的特征向量,按照列拼接的模式。计算图像的整体均值向量。将计算结果、训练样本和待识别的图像样本代入欧氏距离,得到运动损伤图像损伤位置的初步识别结果。然后,通过聚类实现图像分割。聚类分割结果用于对原始图像的像素类别进行颜色描述,计算运动损伤图像中相对损伤比例区域,并识别高强度运动损伤图像的损伤部位。实验结果表明,神经网络的识别率为 80%-100%,该方法的识别时间为 0-0.6/s。该方法可以提高运动损伤图像损伤部位识别的准确性,缩短识别时间,在确定运动损伤部位方面具有一定的可行性。
