IRIS: Interactive Responsive Intelligent Segmentation for 3D Affordance Analysis

Recent advancements in large language and vision-language models have significantly enhanced multimodal understanding, yet translating high-level linguistic instructions into precise robotic actions in 3D space remains challenging. This paper introduces IRIS (Interactive Responsive Intelligent Segmentation), a novel training-free multimodal system for 3D affordance segmentation, alongside a benchmark for evaluating interactive language-guided affordance in everyday environments. IRIS integrates a large multimodal model with a specialized 3D vision network, enabling seamless fusion of 2D and 3D visual understanding with language comprehension. To facilitate evaluation, we present a dataset of 10 typical indoor environments, each with 50 images annotated for object actions and 3D affordance segmentation. Extensive experiments demonstrate IRIS's capability in handling interactive 3D affordance segmentation tasks across diverse settings, showcasing competitive performance across various metrics. Our results highlight IRIS's potential for enhancing human-robot interaction based on affordance understanding in complex indoor environments, advancing the development of more intuitive and efficient robotic systems for real-world applications.

Towards Natural Language-Guided Drones: GeoText-1652 Benchmark with Spatially Relation Matching

Drone navigation through natural language commands remains a significant challenge due to the lack of publicly available multi-modal datasets and the intricate demands of fine-grained visual-text alignment. In response to this pressing need, we present a new human-computer interaction annotation benchmark called GeoText-1652, meticulously curated through a robust Large Language Model (LLM)-based data generation framework and the expertise of pre-trained vision models. This new dataset seamlessly extends the existing image dataset, \ie, University-1652, with spatial-aware text annotations, encompassing intricate image-text-bounding box associations. Besides, we introduce a new optimization objective to leverage fine-grained spatial associations, called blending spatial matching, for region-level spatial relation matching. Extensive experiments reveal that our approach maintains an exceptional recall rate under varying description complexities. This underscores the promising potential of our approach in elevating drone control and navigation through the seamless integration of natural language commands in real-world scenarios.
