A unified framework for local visual descriptors evaluation

作者:

Highlights:

• We propose a new framework to design local visual descriptors.

• Descriptors are decomposed in primitive extraction, coding and aggregation.

• Our framework can explain the most popular descriptors such as HOG, HOF, SURF.

• The framework allows us a rigorous exploration of the possible combinations of primitives, coding and aggregation.

• New descriptors are easily obtained by changing one of the steps of our framework.
