DCE-net will output one alpha/curve parameter map for each channel (RGB) for each iteration. Since the paper use 8 iterations as its default value, DCE-net will output 8 curve parameter maps for each channel, with a total of 24 maps.
The first equation considers alpha for higher-order curves, where α ∈ [−1, 1]. So, the output of DCE-net are 24 scalars. But, this will only produce a global enhancement without considering particular adjustments for some regions of the image. That is the intention of the pixel-wise curve, i.e., your second equation. In this case, DCE-net will output 24 curve parameter maps with the same size as your input image (input = [256, 256, 3], curve map [256, 256, 3]).
Thanks @kkedich. Your explains are exactly. We will release the code soon. It will help understanding how to output curve parameter maps.
The image of the architecture is pretty confusing since the output of the DCE-net apparently has 8 output according to the figure.2 and the paper, which doesn't make sense by looking at the equation provided.
here, in the above equation what exactly is the output of the DCE-net.
and here what is the output
