| dc.description.abstract | Content similarity measurement enables mobile applications to reduce unnecessary computation energy without compromising user visual experience. Existing measures assess the similarity between image frames based on pixels, resulting in non-negligible overhead. This paper presents a lightweight similarity measure called LSIM, which assesses content similarity based on objects in graphics applications. To evaluate the efficacy, we implement LSIM in Android and conduct extensive experiments on a commercial smartphone with various mobile gaming applications. The results show that LSIM is highly correlated with a commonly used pixel-wise measure while incurring nearly zero overhead. We also apply LSIM to a CPU-GPU governing framework to mitigate the rendering of similar frames, thereby reducing the energy consumption by up to 27.3% while maintaining satisfactory visual quality. | en |
