MPSCNNPoolingMax(3) MetalPerformanceShaders.framework MPSCNNPoolingMax(3)NAME
MPSCNNPoolingMax
SYNOPSIS
#import <MPSCNNPooling.h>
Inherits MPSCNNPooling.
Instance Methods
(nonnull instancetype) - initWithDevice:kernelWidth:kernelHeight:strideInPixelsX:strideInPixelsY:
(nullable instancetype) - initWithCoder:device:
Additional Inherited Members
Detailed Description
This depends on Metal.framework Specifies the max pooling filter. For each pixel, returns the maximum value of pixels in the kernelWidth x
kernelHeight filter region.
Method Documentation
- (nullable instancetype) initWithCoder: (NSCoder *__nonnull) aDecoder(nonnull id< MTLDevice >) device
NSSecureCoding compatability See MPSKernel::initWithCoder.
Parameters:
aDecoder The NSCoder subclass with your serialized MPSCNNPooling
device The MTLDevice on which to make the MPSCNNPooling
Returns:
A new MPSCNNPooling object, or nil if failure.
Reimplemented from MPSCNNPooling.
- (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device(NSUInteger) kernelWidth(NSUInteger) kernelHeight(NSUInteger)
strideInPixelsX(NSUInteger) strideInPixelsY
Initialize a MPSCNNPoolingMax pooling filter
Parameters:
device The device the filter will run on
kernelWidth The width of the kernel. Can be an odd or even value.
kernelHeight The height of the kernel. Can be an odd or even value.
strideInPixelsX The output stride (downsampling factor) in the x dimension.
strideInPixelsY The output stride (downsampling factor) in the y dimension.
Returns:
A valid MPSCNNPooling object or nil, if failure.
Reimplemented from MPSCNNPooling.

Detailed Description
This depends on Metal.framework Pooling is a form of non-linear sub-sampling. Pooling partitions the input image into a set of rectangles
(overlapping or non-overlapping) and, for each such sub-region, outputs a value. The pooling operation is used in computer vision to reduce
the dimensionality of intermediate representations.
Method Documentation
- (nullable instancetype) initWithCoder: (NSCoder *__nonnull) aDecoder(nonnull id< MTLDevice >) device
NSSecureCoding compatability See MPSKernel::initWithCoder.
Parameters:
aDecoder The NSCoder subclass with your serialized MPSCNNPooling
device The MTLDevice on which to make the MPSCNNPooling
Returns:
A new MPSCNNPooling object, or nil if failure.
Reimplemented from MPSCNNKernel.
Reimplemented in MPSCNNDilatedPoolingMax, MPSCNNPoolingAverage, MPSCNNPoolingL2Norm, and MPSCNNPoolingMax.
- (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 MPSCNNKernel.
- (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device(NSUInteger) kernelWidth(NSUInteger) kernelHeight

kernelWidth The width of the kernel. Can be an odd or even value.
kernelHeight The height of the kernel. Can be an odd or even value.
Returns:
A valid MPSCNNPooling object or nil, if failure.
- (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device(NSUInteger) kernelWidth(NSUInteger) kernelHeight(NSUInteger)
