The object-centric approach, while beneficial for enhancing retrieval performance, has several limitations:
Neglect of Background Context: Focusing primarily on objects may lead to a lack of understanding of the background context, which can be crucial for interpreting scenes accurately. For example, the setting in which an object appears can significantly influence its meaning.
Limited Handling of Ambiguity: Object-centric methods may struggle with ambiguous scenes where the same object can have different meanings based on its context. For instance, a "bat" could refer to a sports equipment or a flying mammal, depending on the surrounding elements.
Scalability Issues: As the number of objects in a scene increases, the complexity of relationships and interactions can overwhelm the model, leading to performance degradation.
To address these limitations, the object-centric approach can be combined with complementary techniques:
Scene Contextualization: Integrating scene-level features that capture the overall context can enhance understanding. This could involve using scene classification models to provide additional context to the object-centric features.
Temporal Dynamics: In scenarios involving video or sequential images, incorporating temporal information can help the model understand how objects and their relationships evolve over time, providing a richer understanding of the scene.
Multi-Modal Fusion: Combining visual features with other modalities, such as audio or textual descriptions, can provide a more holistic view of the scene. For instance, using audio cues in conjunction with visual data can help disambiguate object meanings.
Hierarchical Learning: Implementing a hierarchical learning approach that first identifies the scene context and then focuses on object relationships can help in managing complexity and improving interpretability.
By integrating these complementary techniques, the limitations of the object-centric approach can be mitigated, leading to a more comprehensive understanding of scenes and improved performance in various applications.
