Just bring a few examples of labeled images and let Custom Vision do the hard work. Since we want to detect whether or not our image is pizza, we’ll be using the classification project type, which tags an entire image. It can also export the AI model in a format that runs directly in Vision AI Dev Kit. Read on to learn more. You, the developer, submit groups of images that feature and lack the characteristics in question. The custom vision API from Microsoft Azure learns to recognise specific content in imagery and becomes smarter with training and time. Once the algorithm is trained, you can test, retrain, and eventually use it in your image recognition app to classify new images. Additional Computer Vision–related capabilities include Form Recognizer to extract key-value pairs and tables from documents, Face to detect and recognize faces in images, Custom Vision to easily build your own computer-vision model from scratch, and Content Moderator to detect unwanted text or images. Find more information about Microsoft’s pricing tiers in their documentation. Computer vision is a tool that is becoming more common in everyday technical projects. Deploy OCR Computer Vision API. Finally, our domain will be food, because we’re analyzing pizza! Azure Custom Vision Service is a Microsoft Cognitive Services product for tagging images using your custom computer vision model. To use the Custom Vision Service you will need to create Custom Vision Training and Prediction resources in Azure. A screen that looks like the following screenshot should pop up. We’re also assuming that we’re putting all sample and test photos inside a folder called photos (hence the definition of dataRoot). Once you’re done setting up Azure, let’s create a custom vision project over at customvision.ai/projects. Yay!
