Apply mask image on an input image
input | Input image to apply the mask on |
mask | Mask to apply |
notMask | If on, the mask is passed through a boolean not before it is used to mask the image. The effect is to pass the input pixels where the mask is zero, and replace the pixels where the mask is non zero |

inlinestatic |
Compare two floating point numbers within tolerance.

Cast the data type of the image to be able to contain the specified value

Get the values contained in the labelmap under the mask
binaryLabelmap | Input image to get values from |
mask | Mask image to get values under |
extent | Can be set to restrict the examined extent to a smaller region. If nullptr, the extent will be the overlapping extent between the label and mask. |
labelValues | The values found in the binary labelmap underneath the mask |
maskThreshold | Threshold value for the mask. Values above this threshold are considered to be under the mask |

Determine if there is a non-zero value in the labelmap under the mask
binaryLabelmap | Input image to get values from |

Determine if a transform is linear and return it if it is. A simple downcast is not enough, as the transform may be a general transform, which can be linear if the concatenation it contains consist of all linear transforms.
transform | Input transform to assess |
linearTransform | Output transform in case transform is linear |

static |
Combines the inputImage and imageToAppend into a new image by max/min operation. The extent will be the union of the two images. Extent can be specified to restrict imageToAppend's extent to a smaller region. inputImage and imageToAppend must have the same geometry, but they may have different extents.
|
static |
Modifies inputImage in-place by combining with modifierImage using max/min operation. The extent will remain unchanged. Extent can be specified to restrict modifierImage's extent to a smaller region. inputImage and modifierImage must have the same geometry (origin, spacing, directions) and scalar type, but they may have different extents.

Resample an oriented image data to match the geometry of a reference geometry matrix. Origin and dimensions are determined from the contents of the input image.
inputImage | Oriented image to resample |
referenceGeometryMatrix | Matrix containing the desired geometry |
outputImage | Output image |
linearInterpolation | True if linear interpolation is requested (fractional labelmap), or false for nearest neighbor (binary labelmap). Default is false. |

inputImage | Oriented image to resample |
referenceImage | Oriented image containing the desired geometry |
outputImage | Output image |
linearInterpolation | True if linear interpolation is requested (fractional labelmap), or false for nearest neighbor (binary labelmap). Default is false. |
padImage | If enabled then it is made sure that the input image's extent fits into the resampled reference image, so if part of the extent is transformed to be outside the reference extent, then it is padded. Disabled by default. |
inputImageTransform | If specified then inputImage will be transformed with inputImageTransform before resampled into referenceImage. |

Transform an oriented image data using a transform that can be linear or non-linear. Linear: simply multiply the geometry matrix with the applied matrix, extent stays the same Non-linear: calculate new extents and change only the extents when applying deformable transform
image | Oriented image to transform |
transform | Input transform |
geometryOnly | Only the geometry of the image is changed according to the transform if this flag is turned on. This flag only has an effect if the transform is non-linear, in which case only the extent is changed. Off by default |
alwaysResample | If on, then image data will be resampled even if the applied transform is linear |
