锚框(anchors)产生：感觉论文这块内容说的不太细致，只能深挖源码了~from __future__ import print_function# --------------------------------------------------------# Faster R-CNN# Copyright (c) 2015 Microsoft# Licensed under The MIT License [see LICENSE for details]# Written by Ro

1.先验框生成Github源码：from __future__ import divisionfrom math import sqrt as sqrtfrom itertools import product as productimport torchclass PriorBox(object): """Compute priorbox coordinates in center-offset form for each source feature map. ""

1.IOU计算：先验框表示方式变换：(cx, cy, w, h) to (xmin, ymin, xmax, ymax):def point_form(boxes): """ Convert prior_boxes to (xmin, ymin, xmax, ymax) representation for comparison to point form ground truth data. Args: boxes: (tensor) center-size
