Local binary pattern computation

Postby wayne » Fri Aug 18, 2017 3:15 am

Hi, I'm trying to use local binary pattern (LBP) for image classification problem on OpenMV M4 module.
It seems that image.find_lbp computes the local binary pattern but there is no detail about how to use this output.
Is there any available information about how to use the output directly and how find_lbp computes ?

Thanks.

Hi, when you have 2 LBP descriptors (d0 and d1) you should use

Code: Select all

image.match_descriptor(d0, d1)
to match. This will return the distance between the two descriptors. Note you can also save and load LBP descriptors.

Hi, is it possible to access the value of LBP descriptor for other processing instead of using image.match_descriptor(d0, d1)?

Thanks again

No that's not implemented.
