Object detection with AI Builder: recognize items in images

Introduction

Object detection is a part of computer vision that lets software identify and locate objects within digital images. In business, this technology is changing the way organizations handle tasks that used to be slow and manual—think inventory tracking, quality checks, or making sure compliance standards are met. By using object detection, businesses can cut down on human mistakes, speed up daily operations, and gain fresh insights from their visual data. For example, a logistics company might rely on object detection to automatically verify what’s inside packages at every step of delivery. In retail, stores can track shelf stock in real time, helping to prevent empty shelves and keeping customers happy.

Microsoft AI Builder is all about making object detection easy for everyone—even if you don’t have a background in programming. As a part of the Power Platform, AI Builder helps “democratize” computer vision by providing no-code and low-code tools. This means your team can add object recognition to business apps without having to call in expert developers. In fact, this is a big reason why more “citizen developers”—business analysts or subject matter experts—are able to create and launch AI solutions themselves. Plus, because AI Builder works hand-in-hand with other Microsoft cloud services like Microsoft Dataverse and Power Automate, it’s easier to keep your data and workflows connected across your entire organization.

Understanding AI Builder Object Detection

What is AI Builder Object Detection?

AI Builder Object Detection is a feature within the Microsoft Power Platform that lets users train models to recognize specific objects in images. These models can be plugged right into apps built with Power Apps, helping automate tasks that depend on visual identification. The secret sauce here is machine learning—these algorithms classify and find objects in images, returning details like what the object is and where it’s located. AI Builder uses deep learning techniques, including convolutional neural networks (CNNs), which are especially good at analyzing images and pulling out the details that matter for object recognition.

Key Components and Features

Object recognition capabilities

AI Builder’s Object Detection can spot and tell apart multiple types of objects in a single image. What’s great is that you can train it to recognize objects unique to your business, not just generic items. For instance, a manufacturer could train a model to identify specific parts on an assembly line, while a healthcare provider might use it to recognize different medical tools in clinical photos. This flexibility means your object detection can be as specialized as your business needs.

Bounding box detection

Bounding boxes are simply rectangles that appear around detected objects in an image. AI Builder uses these to give users a clear visual of what the model is picking up. This is a standard approach in object detection and helps you quickly check if the system is finding the right things. In real life, bounding boxes can help you measure product size or placement on a retail shelf, spot missing items, or even check if required safety equipment is present in a workspace.

Confidence scoring

Each object that gets detected is given a confidence score—that’s basically how sure the model is that it has correctly identified the object. You can set a threshold for these scores, so only results above a certain confidence level are accepted, while anything lower gets flagged for review. For example, in a quality control workflow, items with high-confidence detections might be approved automatically, while any low-confidence results could be sent to a person for a second look. It’s a smart way to balance automation and accuracy.

Prebuilt vs. Custom Models

AI Builder gives you the choice of prebuilt or custom object detection models:

Prerequisites and Setup

To start using AI Builder Object Detection, you’ll need:

• Access to the Microsoft Power Platform (including Power Apps)
• The right AI Builder licensing
• A workspace on the Power Platform
• Appropriate permissions

When gathering images for model training, make sure they’re relevant, clear, and reflect where and how the model will be used. It’s worth considering a quick check-in with your IT or data governance team to be sure your images follow company privacy policies and, if needed, regulations like HIPAA in healthcare or GDPR if you handle personal data.

Creating Your First Object Detection Model

Defining model domain

Setting the model domain means choosing the environment where your object detection model will work best. Picking the right domain—like retail shelves or industrial equipment—helps the model adapt to the specific look and feel of those images. For example, a model for retail will need to handle lots of product arrangements and packaging styles, while an industrial model might need to focus on machinery and deal with tricky lighting.

Providing object names

You’ll need to give names to the objects you want your model to detect. These names serve as labels during training and become the categories your model will look for in new images. Getting these labels right is important, since mistakes here can really hurt the model’s performance. In regulated industries, keeping a clear, well-documented list of object names can also help with audits and compliance.

Image collection requirements

For your model to work well, you need a diverse and big enough set of images. Microsoft suggests at least 15 images per object, but honestly, the more the better—especially if your objects show up in lots of different situations. Try to include photos from different angles, with various lighting and backgrounds. Don’t forget about edge cases, like objects that are partly hidden or shown in unusual ways. These extra details help the model handle real-world surprises.

Training and Optimizing Your Model

Training Process and Best Practices

• Upload labeled images to AI Builder and link each object to its label.
• Ensure a good mix of images.
• Double-check bounding boxes for accuracy.
• Balance the number of images for each object type.
• Review and update your image set as your business changes or you add new items.
• In industries where safety and compliance matter, consider a peer review on labeled images to keep things accurate and traceable.

Model Performance and Testing

Once your model is trained, you’ll want to see how well it performs using metrics like precision and recall. This means testing it with new images and checking if the results match what you expect. Looking at confidence scores and checking the bounding boxes will show if the model is ready for real-world use or if it needs tweaks. Sometimes, it’s smart to run a pilot project in a controlled setting before rolling the model out across your whole operation. This lets you catch any issues early and get feedback from the people who’ll actually use it.

Common Accuracy Issues and Solutions

Common issues include:

• Lack of training data
• Inconsistent labels
• Low-quality images

To improve accuracy:

• Gather more images
• Clean up your labeling
• Improve image clarity
• Retrain your model regularly with new data
• Use data augmentation (rotating, cropping, adjusting brightness) to strengthen your training set

Implementation in Power Apps

Adding Object Detector Component

You can add the Object Detector component right into Power Apps canvas apps, so there’s no need to write custom code. Just link the component to your AI Builder model and set it up to process images from within the app. This makes it easy for frontline workers—like warehouse teams or field techs—to use object detection on their mobile devices, making workflows smoother and cutting down on manual data entry.

Configuring Properties and Settings

Inside Power Apps, you have control over the Object Detector’s properties:

• Choose the model
• Pick where images come from
• Set thresholds for confidence scores

This flexibility helps you fine-tune the component for your specific processes, making sure it fits right in with your app’s logic. For example, you might set it to flag low-confidence results for a supervisor to review, or to automatically send alerts when certain items are detected.

Integration with Business Processes

The results from object detection can trigger other actions in Power Apps or across the broader Power Platform. Detected items can update inventory records, start quality control processes, or send alerts for manual review. When you connect this with Common Data Service or Microsoft Dataverse, your object detection results flow smoothly into other business systems. This kind of integration supports full-scale automation, like kicking off automatic reorder processes when inventory runs low or feeding compliance checks straight into reporting dashboards.

Business Applications and Use Cases

Retail and Inventory Management

In retail, object detection is a real game-changer for tracking inventory. It can spot products on shelves, monitor stock levels, and cut down on the need for manual checks. Automated detection also helps with planogram compliance—making sure products are displayed as planned—and managing out-of-stock situations. For example, grocery stores can use robots with cameras and AI Builder models to scan shelves often, giving them accurate stock data and helping them keep displays looking sharp.

Manufacturing Quality Control

In manufacturing, object detection helps inspect products for defects or missing parts right on the production line. Automated visual checks catch issues faster than manual inspections, leading to better product quality and lower costs. In the auto industry, for instance, object detection can make sure safety-critical parts are present and installed correctly, which not only prevents recalls but also helps meet regulatory standards.

Healthcare Applications

Healthcare relies on object detection for things like analyzing medical images or tracking instruments in surgical trays. This improves accuracy and streamlines clinical workflows, which ultimately benefits patient care. Hospitals can use object detection to double-check that all instruments are present before and after surgeries, which helps prevent mistakes and supports compliance with organizations like The Joint Commission.

Security and Surveillance

Object detection is also key in security and surveillance, where it’s used to spot unauthorized items or monitor restricted spaces. Automated detection of things like vehicles, bags, or equipment means a faster response to security issues. Airports, for example, can use this tech to watch for unattended luggage or restricted items, helping meet TSA regulations and keep travelers safe.
