public class DSpatialConvolve2D_F64
extends DSpatialWindowImage<deepboof.tensors.Tensor_F64,DSpatialPadding2D_F64>
implements DSpatialConvolve2D<deepboof.tensors.Tensor_F64>

Implementation of DSpatialConvolve2D for Tensor_F64.

Local caches of the spatial tensor are used to reduce cache misses. The cache will contain a region across all of the tensor's channels that encompasses the region that a single convolution would interact with. In the backwards pass the local cache is written back into the derivative padded input tensor.
