How to fix makecform error?

iam trying to run door detection code from doordetection in Octave. And there is error

warning: the 'makecform' function belongs to the image package from Octave Forge but has not yet been implemented.

Please read http://www.octave.org/missing.html to learn how you can contribute missing functionality. error: 'makecform' undefined near line 42 column 9 error: called from doordetection at line 42 column 7

how to fix that?

thx

Easy fix: Use MATLAB.

Octave-specific questions should be addressed to an Octave resource.
