E3M: Zero-Shot Spatio-Temporal Video Grounding with Expectation-Maximization Multimodal Modulation

"Spatio-temporal video grounding aims to localize the spatio-temporal tube in a video according to the given language query. To eliminate the annotation costs, we make a first exploration to tackle spatio-temporal video grounding in a zero-shot manner. Our method dispenses with the need for any trai…
