convex

convex ( integer Input, integer Output )

Use this function to build convex halls of objects in a multiphase image or selection. A convex hall can be envisioned as an imaginary elastic string stretched around the object.

Parameters

Input

An integer between 1 and 116 specifying the input image frame number. 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.

Error flags

ERR_OK

The flag set if successful.

ERR_FAILED

The flag set if failed.

Example

This set of statements binarizes a sample image and builds convex halls around interconnected groups of objects:

setCurDir ("samples")

loadIm (1,"sample4.iwd")

threshold (1,1,M_PRESET,0.,113.,TRUE,FALSE)

convex (1,2)
