imaqDanielssonDistance
Usage
int imaqDanielssonDistance(Image* dest, Image* source);
Purpose
Creates a very accurate distance map based on the Danielsson distance algorithm. The function encodes the pixel value of a particle as a function of the distance of the pixel from the particle perimeter. For a faster but less precise algorithm, use imaqSimpleDistance().
Image Types Supported
IMAQ_IMAGE_U8, IMAQ_IMAGE_I16

---|---|---|
dest | Image* | The destination image. |
source | Image* | The image that the function uses to compute the distance map. The function modifies the border of the source image. The border must be at least one pixel wide. |

---|---|
int | On success, this function returns a non-zero value. On failure, this function returns 0. To get extended error information, call imaqGetLastError(). |
Parameter Discussion
source—This function modifies the source image. If you need the original image, create a copy of the image using imaqDuplicate() before using this function.
