Figure 4.

Annotation time performance comparison between RCTA and traditional annotation method. The blue bar represents the time used for the traditional annotation method, and the orange line represents the time used for the RCTA annotation method. The traditional method needs to manually annotate all targets, but RCTA only needs to remove the redundant annotation boxes for augmented images, so the annotation time of RCTA is reduced by over 80% compared to the traditional method as the number of images increases.
