Syntax
class FContiguousSparse2DKernelTransform
Remarks
FContiguousSparse2DKernelTransform
FContiguousSparse2DKernelTransform applies a matrix transformation to an input array. [OutArray] = [[Kernal]][InView]
It provides some optimization by exploit the contiguous and sparse qualities of the kernel rows, which allows it to skip multiplications with the number zero.
It works with non-sparse and non-contiguous kernels as well, but will be more computationally expensive than a naive implementation. Also, only takes advantage of sparse contiguous rows, not columns.
