A unified framework for local visual descriptors evaluation
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.
