Understanding How Vision AI Models Work

Vision AI, though less hyped than large language models (LLMs) like GPT or Claude, is arguably far more capable of transforming industrial spaces. Advanced models like YOLO series, Faster R-CNN, Mask R-CNN, can now achieve real-time object detection, tracking, and compliance on available GPUs. When combined with platforms like DeepStream SDK, these models offer scalable, efficient solutions for managing complex factory environments with hundreds or even thousands of cameras.

Here is how it works. You start by feeding live camera streams into a processing pipeline powered by Vision AI models and platforms like DeepStream SDK. This pipeline transforms raw video data into actionable insights in real-time.

1. Data Input: Camera Feeds: The first step in the Vision AI workflow is the input from cameras, which can range from a few to thousands, depending on the size of the factory. These cameras capture visual data in real-time in RTSP format, which is then fed into the system. 
2. Preprocessing: Data Conditioning: Once the video feeds enter the system, they undergo preprocessing. Preprocessing steps include resizing the video frames, normalizing the data, and, in some cases, applying filters to enhance image quality. This step is crucial for ensuring that the video data is formatted correctly before it is passed through AI models like YOLO or Faster R-CNN for further analysis.
3. Object Detection and Segmentation: After preprocessing, the video frames are analyzed by object detection models such as YOLOv11, Faster R-CNN, or Mask R-CNN. Here’s how each model plays a role here:some text
   • YOLO performs real-time object detection by processing entire images at once, detecting objects, and classifying them at incredible speeds. This is ideal for tracking multiple objects, such as machinery parts, people, or materials on a conveyor belt​.
   • Faster R-CNN improves precision by generating region proposals and focusing on detecting smaller, more detailed objects. This is useful in scenarios like quality control where the identification of minor defects is critical​.
   • Mask R-CNN adds another layer of depth by generating segmentation masks for detected objects. This step is important for tasks requiring pixel-level accuracy, such as monitoring compliance with PPE regulations on the shop floor​.
4. Parallel Processing for Scalability: One of the key strengths of frameworks like DeepStream SDK is its ability to handle multiple streams simultaneously. DeepStream leverages GPU acceleration to process video data in parallel, enabling real-time analytics across hundreds or thousands of cameras. It uses TensorRT for optimizing the AI models, ensuring low-latency, high-performance object detection even in resource-intensive scenarios​.
5. Analytics and Monitoring: After object detection and segmentation, the output is passed through a layer of analytics. This is where the system performs higher-level tasks such as:some text
   • Object tracking, where the movement of detected objects is monitored across video frames.
   • Process mining, where inefficiencies in production lines are identified by analyzing video data in real-time​.
   • Safety compliance checks, ensuring that workers are wearing the proper PPE or that safety protocols are followed.
6. Edge Computing for Low Latency: In cases where real-time decision-making is crucial (e.g., in automated factory processes), edge computing is used to process data close to the source. DeepStream supports edge devices, which can run models like YOLOv11 directly on hardware. This ensures ultra-low-latency responses, ideal for applications that require instant feedback​.
7. Post-Processing and Actionable Insights: After the data is analyzed, the system generates actionable insights in real-time. These insights can trigger automated actions (e.g., halting a production line if a defect is detected) or provide analytics dashboards to factory managers, enabling them to make informed decisions.
8. Scalability and Adaptability: Finally, the system can be scaled and adapted to changing factory conditions. Whether it’s adding new cameras, training models on new data, or updating existing workflows, Vision AI systems like DeepStream offer high flexibility. Integration with cloud-based services can further enhance scalability, allowing even larger deployments​.

This workflow — combining advanced vision models with a scalable platform like DeepStream — allows factories to move beyond manual monitoring and enter a new era of intelligent automation, dramatically improving operational efficiency, safety, and compliance.

Combining Vision Language Models (VLMs) with Vision AI Models

In the second half of 2024, we have seen several Vision Language Models (VLMs) emerge. Some of them are platform models, such as GPT4o or Claude, where you access the model through an API. Others are open models like Llama 3.2-90B-Vision or Pixtral-12B, which are open models that you can deploy in your own infrastructure or on-prem devices. The powerful capability that these models unlock is the ability to analyze individual image frames (not video, yet). 

Why should you combine vision AI models with VLMs? Models like YOLO series can help you build tracking, detection, or counting algorithms, but they can’t explain the scene. This is where VLMs come into the picture. If you can create a workflow where you capture the detected frames, and then use VLMs to explain the scene, you can create alerts that can be integrated into SMS, WhatsApp, and other messaging systems. Doing so means that your team would be able to get immediate feedback on the event.

The best way to explain this is with an example. Imagine your vision model detects a pipeline leakage, and you want to create a system of text alerts that explains the problem at hand, along with the frame of the captured image. By combining Vision AI models with VLMs, you can go beyond detection and add descriptive context, making the output more actionable and insightful. In the pipeline leakage scenario, a Vision AI model such as YOLO could detect the presence and location of a leak. Then, a VLM like Llama 3.2-90B-Vision could analyze and describe the image context, adding details such as the severity or likely cause. This information, paired with real-time alerts, enhances situational awareness and enables prompt, informed responses, improving operational safety and efficiency.

Steps to Combine Vision AI and VLM

To create an effective workflow that scales Vision AI and VLMs across a large camera network, follow these steps:

1. Data Collection and Preprocessing: Begin by gathering image and video data from your cameras. This data should represent a variety of scenarios and lighting conditions specific to your factory.
2. Model Selection and Fine-Tuning: Choose Vision AI models like YOLO or Faster R-CNN for object detection, paired with VLMs like Llama 3.2-90B-Vision for scene interpretation. Fine-tune each model on datasets that reflect your factory’s unique environment, enhancing detection accuracy.
3. Containerization for Deployment: Package both Vision AI and VLM applications in containers for consistent deployment across local servers, edge devices, or the cloud. This allows you to scale easily and manage model versions without disrupting operations.
4. Real-Time Data Processing and Alerts: Set up a workflow where image frames are analyzed in real-time by Vision AI models. The detected frames are then processed by VLMs, which generate descriptive explanations. This output can be formatted as alerts integrated with SMS, WhatsApp, or internal messaging systems, providing immediate feedback to relevant teams.
5. Integration with Legacy Systems: Use APIs to connect your Vision AI and VLMs with existing video management and monitoring systems, ensuring that new insights are added seamlessly to your current infrastructure.
6. Monitoring and Continuous Improvement: Track the system’s performance, adjust models as needed, and re-fine-tune based on any new operational changes. This helps maintain consistent accuracy as your factory environment evolves.

By creating a streamlined workflow, you enable continuous, contextual monitoring across various operational areas, transforming raw video feeds into actionable, insightful data that enhances safety, quality, and efficiency.
