摘要
针对语义分割中存在的边界划分不够准确及存在多尺度目标等问题,提出了一种融合边界监督策略的改进特征金字塔算法。通过融合的边界监督策略和改进的特征金字塔算法分别解决边界划分不准确和存在多尺度目标的问题,并且在上采样过程中加入注意力机制,进一步提升分割效果。实验结果表明:该算法分别在Camvid和PASCAL VOC2012两个数据集上取得了58.69%和78.59%的平均交并比(mean intersection over union,MIOU)指标,在分割效果上有较好的表现。
Aiming at the inaccurate boundary division in semantic segmentation and the existence of multi-scale targets, an improved feature pyramid algorithm fused with boundary supervision strategies is proposed. By fusing the boundary supervision strategy and the improved feature pyramid algorithm, the problems of inaccurate boundary division and the existence of multi-scale targets are sloved respectively,and an attention mechanism is added in the upsampling process to further improve the segmentation effect. The experimental results show that the algorithm can reach 58.69% and 78.59% MIOU(mean intersection over union) indicators on the Camvid and PASCAL VOC2012 data sets respectively, and has a good performance in the segmentation effect.
