Schematic diagram of structure for the PCNN model, which includes an encoding and a decoding part. The leftmost “box” is the input to the DLM and the rightmost “box” is the output, with the different operations (e.g., partial convolution, interpolation, and concatenation) indicated by arrows with different colors. The numbers below each “box” represent the shape of the output data from the various operations.
