Functions boundaries, invmoments, bound2im are used from DIPUM Toolbox, which is available to the purchasers of 'Digital Image Processing Using Matlab' by Rafael C. Gonzalez, Richard E. Woods & Steven L. Eddins. Thanks to them. They will also need some nested functions which are all included in DIPUM toolbox & in the book.

That toolbox is the only one that I found that appears to have a function with that name. I do not know what the function is intended to do. You could consider finding a different implementation of whichever routine you found to extract chain codes.

For example, is the following of any value to you?

i am trying to implement an scanned image of a human hand which is processed i now need to find the area around the trace and i was going to use a freeman chain code to find this and find the c.diff for it. and i seem to having to errors with using the codes from the book discussed due to it not being toolbox available for standard matlab

Why not use the contribution #29518 to create the chain code?
