Introduction
The importance of modern AI models in human-AI interactions is evident in the success of prompt-based universal interfaces like ChatGPT. While tasks related to visual understanding have not received much attention in this context, new studies are starting to emerge. One such task is image segmentation, which involves dividing an image into multiple segments or regions with similar visual characteristics. However, there is a lack of exploration in segmentation models that can interact with humans through various prompts like texts, clicks, images, or a combination of those.
Introducing SEEM: A Groundbreaking Model for Image Segmentation
Researchers from the University of Wisconsin-Madison have presented SEEM, a new approach to image segmentation that utilizes a universal interface and multi-modal prompts. SEEM stands for “Segmenting Everything Everywhere all at once in an image.” This model has four main characteristics: Versatility, Compositionality, Interactivity, and Semantic-awareness.
Versatility allows the model to handle various input prompts such as points, masks, text, boxes, and even references to other images. The model can combine different types of prompts, leading to strong compositional capabilities. Interactivity is achieved through memory prompts that enable the model to interact with other prompts and retain previous segmentation information. Semantic awareness refers to the model’s ability to recognize and label different objects in an image based on their semantic meaning.
Key Features and Architecture
SEEM follows a simple Transformer encoder-decoder architecture with an extra text encoder. All prompts, regardless of their type, are fed into the decoder. The image encoder is used to convert spatial queries into visual prompts, while the text encoder converts textual queries into textual prompts. These prompts are then mapped to a joint visual-semantic space, allowing for unseen user prompts. The model utilizes cross-attention between different prompt types to improve segmentation results.
Benefits and Performance
SEEM demonstrates strong performance on various segmentation tasks, including closed-set and open-set segmentations of different types. It produces masks and semantic labels for objects based on user input prompts, such as clicks, scribbles, or text. The model’s generalization capabilities are also noteworthy, as it can classify new examples from previously unseen classes and segment objects in different frames from movies, even with changing appearances.
Conclusion and Future Developments
SEEM represents a powerful segmentation model that supports a universal and interactive interface for image segmentation. It paves the way for advancements in computer vision similar to those seen in language models. Further improvements can be made by increasing the amount of training data and exploring part-based segmentation. SEEM holds promise for real-world applications and brings us closer to more advanced AI systems.
