Local Ternary Patterns #17

Closed bklare-zz closed 11 years ago

bklare-zz commented 11 years ago

@jklontz - how much time do you estimate it would take you to make a local ternary pattern plugin for openbr? Would be interesting to compare it to LBP. Some researchers prefer LTP over LBP.

Implementation is quite straightforward, issue is computing resources to iterate on finding a good t. Software packages on prior/fisher are really out of date which currently prevents me from running OpenBR there...

If t is exposed as a user defined parameter then it should not be hard to find a roughly optimal value. They provide a default value, which may be useful if we are on the same pixel scale.
