NAME

       MPSNNReduceBinary

SYNOPSIS

       #import <MPSNNReduce.h>

       Inherits MPSCNNBinaryKernel.

       Inherited by MPSNNReduceFeatureChannelsAndWeightsMean, and MPSNNReduceFeatureChannelsAndWeightsSum.

   Instance Methods
       (nonnull instancetype) - initWithDevice:

   Properties
       MTLRegion primarySourceClipRect
       MTLRegion secondarySourceClipRect

   Additional Inherited Members
Detailed Description
       The MPSNNReduce performs a reduction operation The reduction operations supported are:

       o Reduce feature channels mean

Method Documentation
   - (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device
       Standard init with default properties per filter type

       Parameters:
	   device The device that the filter will be used on. May not be NULL.

       Returns:
	   A pointer to the newly initialized object. This will fail, returning nil if the device is not supported. Devices must be
	   MTLFeatureSet_iOS_GPUFamily2_v1 or later.

       Reimplemented from MPSCNNBinaryKernel.

       Reimplemented in MPSNNReduceFeatureChannelsAndWeightsSum, and MPSNNReduceFeatureChannelsAndWeightsMean.

Property Documentation
   - (MTLRegion) primarySourceClipRect [read],	[write],  [nonatomic],	[assign]
       The source rectangle to use when reading data from primary source  A MTLRegion that indicates which part of the primary source to read. If
       the clipRectPrimarySource does not lie completely within the primary source image, the intersection of the image bounds and
       clipRectPrimarySource will be used. The primarySourceClipRect replaces the MPSBinaryImageKernel primaryOffset parameter for this filter.
       The latter is ignored. Default: MPSRectNoClip, use the entire source texture.

       The clipRect specified in MPSBinaryImageKernel is used to control the origin in the destination texture where the min, max values are
       written. The clipRect.width must be >=2. The clipRect.height must be >= 1.

   - (MTLRegion) secondarySourceClipRect [read],  [write],  [nonatomic],  [assign]
       The source rectangle to use when reading data from secondary source  A MTLRegion that indicates which part of the secondary source to read.
       If the clipRectSecondarySource does not lie completely within the secondary source image, the intersection of the image bounds and
       clipRectSecondarySource will be used. The secondarySourceClipRect replaces the MPSBinaryImageKernel secondaryOffset parameter for this
       filter. The latter is ignored. Default: MPSRectNoClip, use the entire source texture.

       The clipRect specified in MPSBinaryImageKernel is used to control the origin in the destination texture where the min, max values are
       written. The clipRect.width must be >=2. The clipRect.height must be >= 1.

NAME

       MPSImageStatisticsMeanAndVariance

SYNOPSIS

       #import <MPSImageStatistics.h>

       Inherits MPSUnaryImageKernel.

   Instance Methods
       (nonnull instancetype) - initWithDevice:
       (nullable instancetype) - initWithCoder:device:

   Properties
       MTLRegion clipRectSource

   Additional Inherited Members
Detailed Description
       The MPSImageStatisticsMeanAndVariance computes the mean and variance for a given region of an image. The mean and variance values are
       written to the destination image at the following pixel locations:

       o mean value is written at pixel location (0, 0)

       o variance value is written at pixel location (1, 0)

Method Documentation
   - (nullable instancetype) initWithCoder: (NSCoder *__nonnull) aDecoder(nonnull id< MTLDevice >) 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.

       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.

       Reimplemented from MPSUnaryImageKernel.

   - (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device
       Specifies information to apply the statistics mean operation on an image.

       Parameters:
	   device The device the filter will run on

       Returns:
	   A valid MPSImageStatisticsMeanAndVariance object or nil, if failure.

       Reimplemented from MPSUnaryImageKernel.

Property Documentation
   - clipRectSource [read],  [write],  [nonatomic],  [assign]
       The source rectangle to use when reading data.  A MTLRegion that indicates which part of the source to read. If the clipRectSource does not
       lie completely within the source image, the intersection of the image bounds and clipRectSource will be used. The clipRectSource replaces
       the MPSUnaryImageKernel offset parameter for this filter. The latter is ignored. Default: MPSRectNoClip, use the entire source texture.

       The clipRect specified in MPSUnaryImageKernel is used to control the origin in the destination texture where the mean value is written.
