|
|
* @brief SeedConnectivity with user defined seeds.
|
||
|
|
*
|
||
|
|
* vtkImageSeedConnectivity marks pixels connected to user supplied seeds.
|
||
|
|
* The input must be unsigned char, and the output is also unsigned char. If
|
||
|
|
* a seed supplied by the user does not have pixel value "InputTrueValue",
|
||
|
|
* then the image is scanned +x, +y, +z until a pixel is encountered with
|
||
|
|
* value "InputTrueValue". This new pixel is used as the seed . Any pixel
|
||
|
|
* with out value "InputTrueValue" is consider off. The output pixels values
|
||
|
|
* are 0 for any off pixel in input, "OutputTrueValue" for any pixels
|
||
|
|
* connected to seeds, and "OutputUnconnectedValue" for any on pixels not
|
||
|
|
* connected to seeds. The same seeds are used for all images in the image
|
||
|
|
* set.
