Path Aggregation Feature Pyramid Network (PAFPN) 1. 解释什么是Feature Pyramid Network(FPN) Feature Pyramid Network(FPN)是一种用于增强深度神经网络对多尺度目标检测能力的网络结构。FPN通过构建一个特征金字塔来强化语义信息。它包含一个自底向上的路径(Bottom-Up Pathway),通过连续的卷积和池化操作提取高层语义信...
即兴趣域池化,用于收集RPN生成的proposals(每个框的坐标),并从(1)中的feature maps中提取出来(从对应位置扣出来),生成proposalsfeature maps送入后续全连接层继续做分类(具体是哪一类别)和回归。 4、Classification and Regression。利用proposals feature maps计算出具体类别,同时再做一次bounding box regression获得检测框...
(只用一个全连接层的解释,不是很理解。for final prediction prevents the issue of collapsing the hiddenspatialfeature map into a short featurevector, which loses spatial information.) 这三个模块的消融试验 参考 Path Aggregation Network for Instance Segmentation解读 Path Aggregation Network for Instance Seg...
Specially, considering the large-scale differences in the objects and the characteristics of small objects in remote sensing imagery, we design a dense path aggregation feature pyramid network (DPAFPN), which can make full use of the high-level semantic information and low-level location information...
Path aggregation U-NetMultimodal MRIDeep learningThe deep neural network has been widely used in semantic segmentation, especially in tumor image segmentation. The segmentation performance of traditional methods cannot meet the high standard of clinical application. In this paper, we propose a new ...
