Gaussian Guided IoU: A Better Metric for Balanced Learning on Object Detection

no code implementations25 Mar 2021 Shengkai Wu, Jinrong Yang, Hangcheng Yu, Lijun Gou, Xiaoping Li

This results in two problems: (1) only one anchor is assigned to most of the slender objects which leads to insufficient supervision information for the slender objects during training and the performance on the slender objects is hurt; (2) IoU can not accurately represent the alignment degree between the receptive field of the feature at the anchor's center and the object.
