The message_update function donot have a smoothness term

[aj161198]

I have been going through your code, and I believe your message-update scheme for min-sum LBP is slightly wrong for two reasons :

1. The smoothness/Binary Potential term is missing in the message update.
2. For a message of a given label, it should take minimum of all labels. But your code doesnot have any such scheme.

Can you please look into the code and check, because I am using your code for message update in some other application?
