• Abstract: Scene context is well known to facilitate humans' perception of visible objects. In this paper, we investigate the role of context in Referring Expression Generation (REG) for objects in images, where existing research has often focused on distractor contexts that exert pressure on the generator. We take a new perspective on scene context in REG and hypothesize that contextual information can be conceived of as a resource that makes REG models more resilient and facilitates the generation of object descriptions, and object types in particular. We train and test Transformer-based REG models with target representations that have been artificially obscured with noise to varying degrees. We evaluate how properties of the models' visual context affect their processing and performance. Our results show that even simple scene contexts make models surprisingly resilient to perturbations, to the extent that they can identify referent types even when visual information about the target is completely missing.

  We show that Vision-Language Models (VLMs) learn to rely on scene contexts in a similar way, when generating references to objects.<n>Our findings show that models leverage scene context adaptively, depending on both the semantic relatedness between object and scene and the level of noise.

  Vanilla visual networks are biased toward learning appearance information, eg texture, to recognize objects. This implicit bias causes the model to fail in detecting novel objects with textures unseen in the open-world setting. We propose view-Consistent LeaRning (v-CLR), which aims to enforce the model to learn appearance-invariant representations for robust instance segmentation.

Our results demonstrate the promise of generative VLM to scale up visual grounding in the real world.

Background objects such as beds, chairs, or wheelchairs can challenge fall detection systems, leading to false positive alarms. We demonstrate that object-specific contextual transformations during training effectively mitigate this challenge.

  We propose a framework, context-guided STVG (CG-STVG), which mines discriminative instance context for object in videos. CG-STVG enjoys object information in text query and guidance from mined instance visual context for more accurate target localization. In our experiments on three benchmarks, including HCSTVG-v1/-v2 and VidSTG, CG-STVG sets new state-of-the-arts in m_tIoU and m_vIoU.

We measure the quality of the generated text by evaluating the capability of a receiver model to accurately identify the described object within the scene. Our results highlight the potential of using pre-trained visual-semantic models for generating high-quality contextual descriptions.

  We propose a novel Contextual Latent Generative Model (Context-LGM), which considers the object-context relation and models it in a hierarchical manner. To infer contextual features, we reformulate the objective function of Variational Auto-Encoder (VAE), where contextual features are learned as a posterior conditioned distribution on the object. The effectiveness of our method is verified by state-of-the-art performance on two context-aware object recognition tasks.

  A layout to image (L2I) generation model aims to generate a complicated image containing multiple objects (things) against natural background (stuff) Existing L2I models have made great progress, but object-to-object and object-to-stuff relations are often broken. We argue that these are caused by the lack of context-aware object and stuff feature encoding in their generators, and location-sensitive appearance representation in their discriminators.
