Representing scenes for real-time context classification on mobile devices

作者：

Highlights：

• A new image descriptor for scene context classification purpose.

• The descriptor is suitable for Image Generation Pipeline of single sensor devices.

• The descriptor is computed directly on compressed domain (JPEG).

• The descriptor is computed in realtime on platform with low computational resources.

• The extraction process does not need extra information (e.g., a visual vocabulary).
