Abstract:
Visual Object Search, the process of locating an object within an image, is a key task in many automated vision systems with applications ranging from surveillance to medical imaging. The task is typically performed using one of two methods: an exhaustive/semi – exhaustive search, or region proposal followed by classification. In practice, reasonable classification accuracies, especially in real time systems, have been achieved by incorporating the latter to avoid expensive searching of the entire scene. However, localizing the object within the scene still presents a challenge to visual object search systems. Hardware acceleration has the potential to remove this dependency by making exhaustive/semi-exhaustive image search feasible from a latency perspective. This work aims to investigate the computational performance benefits of using either method, provided the opportunity for hardware acceleration.
