|
Input
|
|
An integer between 0 and 116 specifying the input image frame number. A value of 0 represents the DMA memory buffer of the video device. Values in the range of 100-116 correspond to hidden frames.
|
|
Output
|
|
An integer between 1 and 116 specifying the output image frame number. Values in the range of 100-116 correspond to hidden frames.
|
|
Grow
|
|
A positive integer specifying the number of thickening steps. If this parameter is set to zero, the function will continue to iterate until the objects are completely thickened.
|
Default value: 0
|
|
Mode
|
|
An enumerated integer that describes the thinning algorithm. Must be one of the following values:
|
|
M_DISTANCE=0 fast non-iterative method based on the distance transform.
|
M_ZHANG=1 parallel iterative method based on the modified Zhang-Suen transform.
|
M_DAVIES=2 sequential iterative method based on the Davies-Plummer algorithm.
|
Default value: M_DISTANCE
|
|
ERR_OK
|
|
The flag set if successful.
|
|
ERR_FAILED
|
|
The flag set if failed.
|
|
This set of statements binarizes a sample image and performs 10 thickening iterations:
|
|
setCurDir ("samples")
|
loadIm (1,"sample4.iwd")
|
threshold(1,1,M_PRESET,0.,113.,TRUE,FALSE)
|
thicken (1,2,10)
