Class MPSNNGramMatrixCalculation

  • All Implemented Interfaces:
    NSCoding, NSCopying, NSSecureCoding, NSObject
    public class MPSNNGramMatrixCalculation
extends MPSCNNKernel
    MPSNNGramMatrixCalculation [@dependency] This depends on Metal.framework The MPSNNGramMatrixCalculation filter specifies a layer which computes the uncentered cross-correlation values between the image planes of each feature channel of an image. If the input image batch is x = x[b, y, x, c], where 'b' is batch index, 'y' and 'x' are the image coordinate and 'c' is the feature channel index then this filter computes the values: y = y[b, 1, f, c] = alpha * sum_{x,y} x[b,y,x,f] * x[b,y,x,c], where 'alpha' is a scaling factor. This operation can be interpreted to be computing all combinations of fully connected layers between the different image planes of the input image. The results are stored in the feature channel and 'x'-coordinate indices of the output batch. The operation is performed independently on different images in the batch. NOTE: Due to the nature of the operation this filter specifies a special padding policy and hence does not support non-default offset or cliprect properties. API-Since: 13.0

                                                      @NotNull java.lang.Object device)
        NSSecureCoding compatability While the standard NSSecureCoding/NSCoding method -initWithCoder: should work, since the file can't know which device your data is allocated on, we have to guess and may guess incorrectly. To avoid that problem, use initWithCoder:device instead.
        Overrides:
        initWithCoderDevice in class MPSCNNKernel
        Parameters:
        aDecoder - The NSCoder subclass with your serialized MPSKernel
        device - The MTLDevice on which to make the MPSKernel
        Returns:
        A new MPSKernel object, or nil if failure.

        Initializes a MPSNNGramMatrixCalculation kernel with scaling factor alpha = 1.0f.
        Overrides:
        initWithDevice in class MPSCNNKernel
        Parameters:
        device - The MTLDevice on which this MPSNNGramMatrixCalculation filter will be used.
        Returns:
        A valid MPSNNGramMatrixCalculation object or nil, if failure.

                                                      float alpha)
        Initializes a MPSNNGramMatrixCalculation kernel.
        Parameters:
        device - The MTLDevice on which this MPSNNGramMatrixCalculation filter will be used.
        alpha - Scaling factor for the output.
        Returns:
