Fig. 2:

Network structure of our phase recognition system. Shown are the convolution kernel sizes for each network stage Conv1-Res5) and the dimension transformation of the features in the nonlocal blocks. The W_α, W_β, and W_γ are the parameters of nonlocal blocks in equation 2 and 3. The “f” and “C” in the progress gate module (dash-lined block on the left of the middle row) are the function and the condition introduced in Section 2.5.
