Introducing PhysObjects: A Comprehensive Dataset of 36.9K Crowd-Sourced and 417K Automated Physical Concept Annotations for Common Household Objects

Welcome to the fascinating world of Visual Language Models (VLMs), where images and text come together to create a comprehensive understanding of the world around us. In this blog post, we will explore the latest research on VLMs and delve into the exciting possibilities they bring.

Imagine an AI system that can not only process text but also understand and analyze images and videos. This is the power of VLMs, bridging the gap between natural language understanding and computer vision. With VLMs, we can generate rich and contextually relevant descriptions, stories, or explanations that incorporate both textual and visual elements. Just imagine the possibilities for marketing, entertainment, and education!

One of the key tasks of VLMs is visual question answering, where an AI model is presented with an image and a text-based question about that image. The model uses computer vision techniques to analyze the image and processes the textual question using natural language processing (NLP). The output is an answer that reflects the image’s content and addresses the specific query in the question. Another important task is image captioning, where VLMs generate descriptive textual captions or sentences to explain the content of an image.

However, current VLMs have limitations in capturing physical concepts like material type and fragility of common objects. This poses a challenge for robotic identification tasks that require physical reasoning. To overcome this, researchers from Stanford, Princeton, and Google Deep Mind have proposed “PhysObjects.” It is an object-centric dataset that includes crowd-sourced and automated physical concept annotations of common household objects.

By fine-tuning VLMs on the PhysObjects dataset, the researchers have achieved significant improvements in physical reasoning abilities. Their physically-grounded VLM outperforms other models in predicting physical concepts on a held-out dataset example. They also combined this physically grounded VLM with an LLM-based robotic planner, demonstrating its advantages in tasks that require physical reasoning.

The researchers used the EgoObjects dataset as their image source, which is the largest object-centric dataset of real objects publicly available. This dataset, consisting of videos of realistic household arrangements, is highly relevant to the training of household robotics. With an abundance of images, objects, and object instance IDs, the EgoObjects dataset provides a comprehensive training ground for VLMs.

The results of this research show promising improvements in planning performance for tasks that involve physical reasoning. The researchers are now focused on expanding their work beyond physical reasoning and exploring areas such as geometric reasoning and social reasoning. This methodology and dataset lay the foundation for more sophisticated reasoning using VLMs in robotics.
