WebSecondly, a structure aware scribble extension module (SASEM) is designed to recover building structures from scribbles through effective utilization of edge features. Finally, an edge-structureaware loss is proposed to limit the scope of the restored structure. Web13 aug. 2024 · 3.2 Double IoU-aware In the introduction section, we mentioned that the correlation between the classification score and the localization accuracy is low on the one-stage detectors. This low correlation hurts the Average Precision (AP) of the models in two ways during inference.
