public class MPSImageDilate
extends MPSUnaryImageKernel

MPSImageDilate

The MPSImageDilate finds the maximum pixel value in a rectangular region centered around each pixel in the source image. It is like the MPSImageAreaMax, except that the intensity at each position is calculated relative to a different value before determining which is the maximum pixel value, allowing for shaped, non-rectangular morphological probes. [@code] for each pixel in the filter window: value = pixel[filterY][filterX] - filter[filterY*filter_width+filterX] if( value > bestValue ){ result = value bestValue = value; } [@endcode] A filter that contains all zeros and is identical to a MPSImageAreaMax filter. The center filter element is assumed to be 0 to avoid causing a general darkening of the image.

The edgeMode property is assumed to always be MPSImageEdgeModeClamp for this filter.

init

public MPSImageDilate init()

Overrides:

init in class MPSUnaryImageKernel

initWithDevice

public MPSImageDilate 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.

initWithDeviceKernelWidthKernelHeightValues

public MPSImageDilate initWithDeviceKernelWidthKernelHeightValues(MTLDevice device,
                                                                  long kernelWidth,
                                                                  long kernelHeight,
                                                                  org.moe.natj.general.ptr.ConstFloatPtr values)

Init a object with kernel height, width and weight values.

Each dilate shape probe defines a 3D surface of values. These are arranged in order left to right, then top to bottom in a 1D array. (values[kernelWidth*y+x] = probe[y][x]) Values should be generally be in the range [0,1] with the center pixel tending towards 0 and edges towards 1. However, any numerical value is allowed. Calculations are subject to the usual floating-point rounding error.

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.

values - The set of values to use as the dilate probe. The values are copied into the filter. To avoid image ligthening or darkening, the center value should be 0.0f.

kernelHeight

public long kernelHeight()

[@property] kernelHeight

The height of the filter window. Must be an odd number.

kernelWidth

public long kernelWidth()

[@property] kernelWidth

The width of the filter window. Must be an odd number.

initWithCoder

public MPSImageDilate initWithCoder(NSCoder aDecoder)

Description copied from interface: NSCoding

NS_DESIGNATED_INITIALIZER

Specified by:

initWithCoder in interface NSCoding

Overrides:

initWithCoder in class MPSUnaryImageKernel

initWithCoderDevice

public MPSImageDilate 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 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
