作者提出的FPN(Feature Pyramid Network)算法同时利用低层特征高分辨率和高层特征的高语义信息,通过融合这些不同层的特征达到预测的效果。并且预测是在每个融合后的特征层上单独进行的,这和常规的特征融合方式不同。 期待代码 2.。 博客二 论文地址:Feature Pyramid Networks for Object Detection Github:https://github...
2. 结构(Architecture) 下图所示的三种结构是在目标检测中比较常见的结构: 图1 常见结构 (a) Featurized image pyramid:这种方式就是先把图片弄成不同尺寸的,然后再对每种尺寸的图片提取不同尺度的特征,再对每个尺度的特征都进行单独的预测,这种方式的优点是不同尺度的特征都可以包含很丰富的语义信息,但是缺点就是...
