All Superinterfaces:
Function<T>
All Known Implementing Classes:
SpatialConvolve2D_F32, SpatialConvolve2D_F64

extends Function<T>
Performs convolutions across an input image with special kernels that have 'C' channels, one for each input image.

  • Method Details

    • forward

      void forward​(T input, T output)
      Applies forward spacial convolution. Each spacial convolution kernel is composed of a C 2D kernels that are applied to the input image. The number of channels in the output image is dependent on the number of spacial kernels in this layer. 
       Input   shape = (N, C, H,  W)
 Outputs shape = (N, F, H', W')
 Weight  shape = (F, C, HH, WW)
 Bias    shape = (F,)
 -------------------------------------------------
 N   = Size of mini-batch
 C   = Number of channels in input image
 H   = Height of input image
 W   = With of input image
 F   = Number of kernels or channels in output
 H'  = Height of output image. H' = 1 + (H + padY0 + padY1 - HH) / periodY
 W'  = Width of output image.  W' = 1 + (W + padX0 + padX1 - WW) / periodX
 HH  = Height of kernel
 WW  = Width of kernel
