为准确提取人体轮廓,提出基于MINet模型的复杂背景人体轮廓提取方法.拍摄正、侧面人体全身照并标注掩膜图,匹配不同的复杂背景,融合形成2860张多场景下的人像数据集.利用迁移学习机制,优化MINet显著目标检测模型,提取人体轮廓.分别对比了基于迁移学习的策略与原模型、U2 Net显著目标检测模型、Mediapipe人体轮廓提取算法和传统阈值分割算法的人体轮廓提取效果.结果表明:基于迁移学习的MINet模型具有最优的人体轮廓提取性能,其准确率、精度、召回率和综合指标分别达到了0.998、0.987、0.992和0.990,人体轮廓提取效果与标注的掩模图最为近似.该方法能低成本、批量化、快速提取图像中的人体轮廓,为远程服装定制中的照片测量提供有效的技术方法.
Automatic Extraction of Human Body Contours in Complex Background Images
To accurately extract human body contours,a method for complex background human body contour ex-traction based on the MINet model was proposed.Front-view and side-view human images were captured,and cor-responding mask images were annotated.Diverse complex backgrounds were matched with portraits to create a data-set of 2860 portraits across various scenes.Using a transfer learning mechanism,the MINet salient object detection model was optimized to extract human body contours.The human contour extraction effects of the transfer learn-ing-based MINet model were compared with the original model,the U2Net salient object detection model,the Media-pipe human contour extraction algorithm,and a traditional threshold-based segmentation algorithm.The results show that the transfer learning-based MINet model demonstrates optimal performance in human body contour extrac-tion,with precision,accuracy,recall,and the composite metric F1 reaching 0.998,0.987,0.992,and 0.990,respectively,closely resembling the annotated mask images.This method offers a cost-effective,scalable,and fast approach to extract human body contours from images,providing an effective technique for photo measurement in remote clothing customization.
