WebApr 13, 2024 · Modern R-CNN based detectors apply a head to extract Region of Interest (RoI) features for both classification and localization tasks. In contrast, we found that these two tasks have opposite preferences towards two widely used head structures (i.e. fully connected head and convolution head). Specifically, the fully connected head is more … WebDouble heading is a useful practice on single lines even in the absence of a need for more power, as to double-head a train saves making a separate path for a spare engine; it …
