MPSImageAreaMax(3) MetalPerformanceShaders.framework MPSImageAreaMax(3) NAME
MPSImageAreaMax SYNOPSIS
#import <MPSImageMorphology.h> Inherits MPSUnaryImageKernel. Inherited by MPSImageAreaMin. Instance Methods (nonnull instancetype) - initWithDevice:kernelWidth:kernelHeight: (nullable instancetype) - initWithCoder:device: (nonnull instancetype) - initWithDevice: Properties NSUInteger kernelHeight NSUInteger kernelWidth Additional Inherited Members 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.

MPSCNNPooling(3) MetalPerformanceShaders.framework MPSCNNPooling(3) NAME
MPSCNNPooling SYNOPSIS
#import <MPSCNNPooling.h> Inherits MPSCNNKernel. Inherited by MPSCNNDilatedPoolingMax, MPSCNNPoolingAverage, MPSCNNPoolingL2Norm, and MPSCNNPoolingMax. Instance Methods (nonnull instancetype) - initWithDevice:kernelWidth:kernelHeight: (nonnull instancetype) - initWithDevice:kernelWidth:kernelHeight:strideInPixelsX:strideInPixelsY: (nullable instancetype) - initWithCoder:device: (nonnull instancetype) - initWithDevice: Additional Inherited Members 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 Initialize a 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. Returns: A valid MPSCNNPooling object or nil, if failure. - (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device(NSUInteger) kernelWidth(NSUInteger) kernelHeight(NSUInteger) strideInPixelsX(NSUInteger) strideInPixelsY Initialize a 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 in MPSCNNPoolingAverage, MPSCNNPoolingL2Norm, and MPSCNNPoolingMax.
