public class MPSImageLaplacian
extends MPSUnaryImageKernel

MPSImageLaplacian

The MPSImageLaplacian is an optimized variant of the MPSImageConvolution filter provided primarily for ease of use. This filter uses an optimized convolution filter with a 3 x 3 kernel with the following weights: [ 0 1 0 1 -4 1 0 1 0 ]

The optimized convolution filter used by MPSImageLaplacian can also be used by creating a MPSImageConvolution object with kernelWidth = 3, kernelHeight = 3 and weights as specified above.

bias

public float bias()

[@property] bias

The bias is a value to be added to convolved pixel before it is converted back to the storage format. It can be used to convert negative values into a representable range for a unsigned MTLPixelFormat. For example, many edge detection filters produce results in the range [-k,k]. By scaling the filter weights by 0.5/k and adding 0.5, the results will be in range [0,1] suitable for use with unorm formats. It can be used in combination with renormalization of the filter weights to do video ranging as part of the convolution effect. It can also just be used to increase the brightness of the image.

Default value is 0.0f.

init

public MPSImageLaplacian init()

Overrides:

init in class MPSUnaryImageKernel

initWithDevice

public MPSImageLaplacian initWithDevice(java.lang.Object device)

Description copied from class: MPSUnaryImageKernel

Standard init with default properties per filter type

Overrides:

initWithDevice in class MPSUnaryImageKernel

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.

setBias

public void setBias(float value)

[@property] bias

The bias is a value to be added to convolved pixel before it is converted back to the storage format. It can be used to convert negative values into a representable range for a unsigned MTLPixelFormat. For example, many edge detection filters produce results in the range [-k,k]. By scaling the filter weights by 0.5/k and adding 0.5, the results will be in range [0,1] suitable for use with unorm formats. It can be used in combination with renormalization of the filter weights to do video ranging as part of the convolution effect. It can also just be used to increase the brightness of the image.

Default value is 0.0f.

initWithCoder

public MPSImageLaplacian initWithCoder(NSCoder aDecoder)

Description copied from interface: NSCoding

NS_DESIGNATED_INITIALIZER

Specified by:

initWithCoder in interface NSCoding

Overrides:

initWithCoder in class MPSUnaryImageKernel

initWithCoderDevice

public MPSImageLaplacian initWithCoderDevice(NSCoder aDecoder,
                                             java.lang.Object device)

Description copied from class: MPSUnaryImageKernel

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 MPSUnaryImageKernel

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.

supportsSecureCoding

public static boolean supportsSecureCoding()

_supportsSecureCoding

public boolean _supportsSecureCoding()

Description copied from interface: NSSecureCoding

This property must return YES on all classes that allow secure coding. Subclasses of classes that adopt NSSecureCoding and override initWithCoder: must also override this method and return YES. The Secure Coding Guide should be consulted when writing methods that decode data.

Specified by:

_supportsSecureCoding in interface NSSecureCoding

Overrides:

_supportsSecureCoding in class MPSUnaryImageKernel
