Detailed Description

template<class InputStorageType, class OutputStorageType>
class BIAS::DistTransform< InputStorageType, OutputStorageType >

Class for calculating the distance transform.

Generates an image where for all pixels the distance to the step of pixels with zero value in the input image is calculated. The Borgefor distance is used to measure distances (diagonal step has distance 4, horizontal/vertical step has distance 3).

Member Enumeration Documentation

template<class InputStorageType, class OutputStorageType>
enum BIAS::FilterBase::TBorderHandling
inherited

enum for border calculation, same meanings as in matlab:

  • TBH_valid: returns only the pixels whose values can be computed without using zero padding of the input image. The resulting output image is smaller than the input image. The ROI of the output image is set accordingly.
  • TBH_same: returns the set of pixels that can be computed by applying the filter to all pixels that are actually part of the input image. Border pixels are computed using zero padding, but the center pixel of the computational kernel is applied only to pixels in the image. This results in an output image that is the same size as the input image.
  • TBH_full: returns the full convolution. This means conv2 returns all pixels for which any of the pixels in the computational molecule overlap pixels in the image, even when the center pixel is outside the input image. The resulting output image is larger than the input image. This is not implemented at the moment.

run over all pixel which do not belong to the roi and set them to the value in the source image regardless of the roi of the source.

Both images must have same size.

int DistTransform::Filter ( const Image< InputStorageType > &  src,
BIAS::Image< OutputStorageType > &  dist_img 
)
virtual

Calculates the distanceImage from source image src.

Converts the given image to a distance transformed image (the Borgefor distance is used, that means one step in diagonal direction has a distance of 4 other steps have distances of 3);
The pixel set, to which the distance is calculated has to be marked as zero valued pixels, e.g. grey value zero or SetZeroLevel().
