    We propose DeepFind, an on-device acceleration engine for mobile-native spatial exploratory applications that utilize deep-learning architectures such as CNNs. DeepFind leverages the fact that input frames exhibit high visual dynamicity, of which a dominant portion actually comes from the camera’s own motion. We develop lightweight sensor-based transformations and perspective-normalized global buffer management to replace expensive convolution operations, effectively speeding up CNN inference. DeepFind achieves a win-win – lightweight reusability determination coupled with avoiding a large amount of convolution operations, creating a virtuous cycle: smaller inter-frame differential leads to faster per-frame computation, yielding even smaller inter-frame differential and so on.
