Figure 3.
At the left, the word input appears with a right-pointing arrow. A dashed rectangular outline labelled Coding Module one contains five rounded rectangular blocks labelled C B L. An arrow leads from Coding Module one to a dashed rectangular outline labelled Coding Module two, which also contains five rounded rectangular blocks labelled C B L. A downward arrow from the connection between the two coding modules leads to a block labelled T C B L under the text Decoding Module one. Another downward arrow from Coding Module two leads to a second block labelled T C B L under the text Decoding Module two. Arrows from both T C B L blocks point to a central trapezoid labelled splice. A downward arrow extends from splice to a right-pointing arrow. A legend at the bottom includes a rounded block labelled C B L with the text Conv Layer plus B N Layer plus Re L U, and another rounded block labelled T C B L with the text TransposeConv Layer plus B N Layer plus Re L U.Schematic diagram of 2D feature extraction encoding and decoding
