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.

MPSImageAreaMax
SYNOPSIS
#import <MPSImageMorphology.h>
Inherits MPSUnaryImageKernel.
Inherited by MPSImageAreaMin.

Detailed Description
MPSImageMorphology.h MetalPerformanceShaders
Copyright:
Copyright (c) 2015 Apple Inc. All rights reserved. MetalPerformanceShaders morphological operators
The MPSImageAreaMax kernel finds the maximum pixel value in a rectangular region centered around each pixel in the source image. If there
are multiple channels in the source image, each channel is processed independently. The edgeMode property is assumed to always be
MPSImageEdgeModeClamp for this filter.
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
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 MPSUnaryImageKernel.
- (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device(NSUInteger) kernelWidth(NSUInteger) kernelHeight
Set the kernel height and width
Parameters:
device The device the filter will run on
kernelWidth The width of the kernel. Must be an odd number.
kernelHeight The height of the kernel. Must be an odd number.
Property Documentation
- kernelHeight [read], [nonatomic], [assign]
The height of the filter window. Must be an odd number.
- kernelWidth [read], [nonatomic], [assign]
The width of the filter window. Must be an odd number.
