Downsampling formula
WebThe backbone contains five downsampling operations, and we obtain feature maps with a size of 32 × 16 after the final downsampling. The output has two branches: a classification branch with a size of 32 × 16 × 1 output tensor and a location branch with a size of 32 × 16 × 8 output tensor.
