Class

MPSCNNConvolution

A convolution kernel that convolves the input image with a set of filters, with each producing one feature map in the output image.

Declaration

class MPSCNNConvolution : MPSCNNKernel

Overview

The attributes of a convolution operation are described by an MPSCNNConvolutionDescriptor object.
