Descriptors

descriptors_2d is a package for providing a common interface to many different image descriptors. Currently, the descriptors that are recommended for use are:

• Superpixel color histogram
• SURF
• HOG
• Daisy

The daisy descriptor is currently in descriptors_2d_gpl until we can get it BSD licensed.

Notes

• descriptor.getName() is guaranteed to be unique for any setting of parameters.

• All descriptors work with both BGR and grayscale (IPL_DEPTH_8U) images unless otherwise noted.

• SURF will give you different numbers on 32 and 64bit machines, at least in our tests.
