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.
