Distance Transform Functions
This section describes the distance transform functions.
Distance transform is used for calculating the distance to an object. The input is an image with feature and non-feature pixels. The function labels every non-feature pixel in the output image with a distance to the closest feature pixel. Feature pixels are marked with zero.
Distance transform is used for a wide variety of subjects including skeleton finding and shape analysis.
- DistanceTransform
Calculates distance to the closest zero pixel for all non-zero pixels of source image. - GetDistanceTransformMask
Returns an optimal mask for a given type of metrics and given mask size. - FastMarchingGetBufferSize
Computes the size of the working buffer for the peak search. - FastMarching
Calculates distance transform to closest zero pixel for all non-zero pixels of source image using fast marching method. - TrueDistanceTransformGetBufSize
Calculates the size of the temporary working buffer for the function ippiTrueDistanceTransform. - TrueDistanceTransform
Calculates the Eucledian distance to the closest zero pixel for all non-zero pixels of the source image.
