basicsr.archs.ecbsr_arch

class basicsr.archs.ecbsr_arch.ECB(in_channels, out_channels, depth_multiplier, act_type='prelu', with_idt=False)[source]

Bases: Module

The ECB block used in the ECBSR architecture.

Paper: Edge-oriented Convolution Block for Real-time Super Resolution on Mobile Devices Ref git repo: https://github.com/xindongzhang/ECBSR

Parameters:

  • in_channels (int) – Channel number of input.

  • out_channels (int) – Channel number of output.

  • depth_multiplier (int) – Width multiplier in the expand-and-squeeze conv. Default: 1.

  • act_type (str) – Activation type. Option: prelu | relu | rrelu | softplus | linear. Default: prelu.

  • with_idt (bool) – Whether to use identity connection. Default: False.

forward(x)[source]

Define the computation performed at every call.

Should be overridden by all subclasses.

Note

Although the recipe for forward pass needs to be defined within this function, one should call the Module instance afterwards instead of this since the former takes care of running the registered hooks while the latter silently ignores them.
