Face detection in distributed edge computing is confronting challenges such as loss of facial features due to occlusions,insufficient feature of small-scale faces,and difficulty in efficient deployment on distributed terminals.In this paper,an improved you only look once version 12 nano(YOLOv12n)is proposed,specifically designed to promote the detection of occluded and small-scale faces in distributed edge computing.A spatial-to-depth convolution(SPD-Conv)is introduced to optimize feature extraction and reconstruct feature encoding.A cross stage partial receptive field enhancement module(C3RFEM)is integrated to strengthen modeling capability for occluded and small-scale faces by multi-branch dilated convolutions.A multi-patch Monte Carlo attention(MPMCA)is proposed to elevate robustness and adaptability by random perturbations.A shapeaware normalized Wasserstein distance(SA-NWD)is adopted to increase the accuracy of localization and shape modeling for small targets.Experimental results demonstrate the proposed model achieves improvements in mean average precision 50(mAP50)with increase of 0.92%,1.20%and 3.44%on the Easy,Medium and Hard subsets of the WiderFace dataset compared to the original YOLOv12n,with enhanced robustness and adaptability in distributed edge computing. 展开更多
