Attend What You Need: Motion-Appearance Synergistic Networks for Video Question Answering

Online video dilemma answering endeavor aims at reasoning above larger-amount eyesight-language interactions. Here, not only concerns about the appearance of objects are introduced, as in static picture dilemma answering, but also concerns pertaining to motion and causality.

Common products can’t assess movement as object detection products absence temporal modeling. As a result, a modern review proposes Movement-Visual appeal Synergistic Networks for video dilemma answering.

The approach consists of a few modules: movement, appearance, and movement-appearance fusion. First of all, object graphs are made via graph convolutional networks (GCNs), and interactions involving objects in just about every visual element are computed. Then, cross-modal grounding is executed involving the output of the GCNs and the dilemma capabilities. Experimental benefits display the performance of the proposed architecture when compared to other products.

Online video Query Answering is a endeavor which requires an AI agent to response concerns grounded in video. This endeavor entails a few critical problems: (one) fully grasp the intention of various concerns, (two) capturing various components of the enter video (e.g., object, motion, causality), and (3) cross-modal grounding involving language and eyesight data. We propose Movement-Visual appeal Synergistic Networks (MASN), which embed two cross-modal capabilities grounded on movement and appearance data and selectively employ them relying on the question’s intentions. MASN consists of a movement module, an appearance module, and a movement-appearance fusion module. The movement module computes the motion-oriented cross-modal joint representations, even though the appearance module focuses on the appearance element of the enter video. Ultimately, the movement-appearance fusion module can take just about every output of the movement module and the appearance module as enter, and performs dilemma-guided fusion. As a result, MASN achieves new state-of-the-artwork effectiveness on the TGIF-QA and MSVD-QA datasets. We also perform qualitative investigation by visualizing the inference benefits of MASN.
