watershed
|
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.
|
|
Preflood
|
|
An integer specifying the initial depth of "water basins" on the intensity surface. Increasing this parameter will submerge the smaller ridges and they will not appear in the output image.
|
Default value: 0
|
|
Invert
|
|
A boolean integer specifying whether the input image should be inverted before the operation is applied. Must be one of the following values:
|
|
FALSE=0 no inversion is performed.
|
TRUE=1 inverts the input image before applying the watershed algorithm. The valleys in the image intensity will be extracted instead of the ridges.
|
Default value: FALSE
|
|
|
ERR_OK
|
|
The flag set if successful.
|
|
ERR_FAILED
|
|
The flag set if failed.

median(1,1,7)
