This function determines the shortest distance between each blob pixel and the blob's background, and assigns this distance to the pixel. It produces a type of contour mapping of a blob.
Specifies the identifier of the source of the operation. This parameter must be given an image buffer identifier.
This image buffer must not have a region of interest (ROI) associated with it. Using an image buffer with an ROI will cause an error.
The source image buffer must be unsigned monochrome 8- or 16-bit, M_BGR32 packed, or floating-point.
Specifies the identifier of the destination of the resulting image. This parameter must be given an image buffer identifier.
This image buffer must not have a region of interest (ROI) associated with it. Using an image buffer with an ROI will cause an error.
The destination buffer is always treated as unsigned.
Specifies the way in which the minimum distance from blob pixel to background pixel is calculated. This parameter approximates the true distance from blob pixel to background pixel using a 3x3 distance matrix and can be set to one of the following:

| M_CHAMFER_3_4 |
Determines the minimum distance using horizontal, vertical or diagonal pixel steps. Horizontal and vertical steps are counted as 3; diagonal steps are counted as 4. Then, the resulting distance is normalized by a factor of 3. This transform provides the best approximation to Euclidean distance. This transform requires that the destination buffer be deep enough to hold a number at least three times the maximum distance from a blob pixel to its edge. For example, an 8-bit buffer (255 max) can be used for a maximum distance of 85 pixels and a 16-bit buffer (65535 max) for a maximum distance of 21845 pixels. 3x3 Distance Matrix:
