public class MPSImageFindKeypoints
extends MPSKernel

MPSImageFindKeypoints

The MPSImageFindKeypoints kernel is used to find a list of keypoints whose values are >= minimumPixelThresholdValue in MPSImageKeypointRangeInfo. The keypoints are generated for a specified region in the image. The pixel format of the source image must be MTLPixelFormatR8Unorm.

Encode the filter to a command buffer using a MTLComputeCommandEncoder.

The filter will not begin to execute until after the command buffer has been enqueued and committed.

Parameters:

commandBuffer - A valid MTLCommandBuffer.

source - A valid MTLTexture containing the source image for the filter.

regions - An array of rectangles that describe regions in the image. The list of keypoints is generated for each individual rectangle specifed.

keypointCountBuffer - The list of keypoints for each specified region

keypointCountBufferOffset - Byte offset into keypointCountBufferOffset buffer at which to write the keypoint results. Must be a multiple of 32 bytes.

keypointDataBuffer - A valid MTLBuffer to receive the keypoint data results for each rectangle. The keypoint data for keypoints in each rectangle are stored consecutively. The keypoint data for each rectangle starts at the following offset: MPSImageKeypointRangeInfo.maximumKeyPoints * rectangle index

keypointDataBufferOffset - Byte offset into keypointData buffer at which to write the keypoint results. Must be a multiple of 32 bytes.

init

public MPSImageFindKeypoints init()

Overrides:

init in class MPSKernel

initWithCoder

public MPSImageFindKeypoints initWithCoder(NSCoder aDecoder)

Description copied from interface: NSCoding

NS_DESIGNATED_INITIALIZER

Specified by:

initWithCoder in interface NSCoding

Overrides:

initWithCoder in class MPSKernel

initWithCoderDevice

public MPSImageFindKeypoints initWithCoderDevice(NSCoder aDecoder,
                                                 java.lang.Object 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.

Overrides:

initWithCoderDevice in class MPSKernel

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.

initWithDevice

public MPSImageFindKeypoints initWithDevice(java.lang.Object device)

Description copied from class: MPSKernel

Standard init with default properties per filter type

Overrides:

initWithDevice in class MPSKernel

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.

initWithDeviceInfo

public MPSImageFindKeypoints initWithDeviceInfo(MTLDevice device,
                                                MPSImageKeypointRangeInfo info)

Specifies information to find keypoints in an image.

Parameters:

device - The device the filter will run on

info - Pointer to the MPSImageKeypointRangeInfo struct

Returns:

A valid MPSImageFindKeypoints object or nil, if failure.
