Perform a Euclidean Distance Transform

- (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

Specifies information to apply the statistics min-max operation on an image.

Parameters:

device The device the filter will run on

Returns:

A valid MPSImageEuclideanDistanceTransform object or nil, if failure.

Reimplemented from MPSUnaryImageKernel.
