- 30. What is it? Custom Vision Service is an easy-to-use tool for prototyping, improving, and deploying a custom image classifier to a cloud service, without any background in computer vision or deep learning required. Model
- 31. Object Detection
- 32. Building a Classifier • Create a project • Select a domain • Add images • Assign tags to images • Train the classifier • Evaluate the classifier
- 33. Classifiers and Projects A classifier is a model you build using Custom Vision Service, by using a few training images. Each classifier you build is in its own project. Classifier = Project
- 34. Domains When you create a project, you select a domain for that project. The domain optimizes a classifier for a specific type of object in your images. • Food Optimized for dishes you would see on a restaurant menu. • Landmark Optimized for recognizable landmarks, both natural and artificial. • Retail Optimized for classifying images in a shopping catalog or shopping website. • Adult Optimized to better define between adult content and non-adult content.
- 35. Training Images To create a high precision classifier, Custom Vision Service needs several training images. A training image is a photograph of the image you want Custom Vision Service to classify.
- 36. Iteration Every time you Train or re-train your classifier, you create a new iteration of your model.
- 37. Testing a Model After you train your model, you can quickly test it using a locally stored image or an online image. The test uses the most recently trained iteration.
- 38. Important Terms Precision When you classify an image, how likely is your classifier to correctly classify the image? Recall Out of all images that should have been classified correctly, how many did your classifier identify correctly?
- 39. Using the Prediction API After a successful training, the Custom Vision Service can be accessed via an endpoint that references the Project Identifier, as long as the appropriate Prediction Key is passed in the request header.
- 40. Prediction API REST Concepts All actions related to the Custom Vision Service are accessed via standard REST- based methods, such as GET and POST against an API endpoint, making it simple to use the Prediction API on any platform or with any programming language.
- 41. Train in the Cloud, Run Anywhere Train in Custom Vision Service Deploy & Run Anywhere
- 42. Commonly Used APIs PredictionTraining • Createimages • Tagimages • Createprojects • Manageprojects • Manageiterations • Createtags • Getaccountinformation • Trainaproject • Predictimages • Predictandsaveimages • PredictimageURLs • PredictandsaveimageURLs
- 43. Improving a Classifier The best way to have a quality classifier is to add more varied tagged images (different backgrounds, angles, object size, groups of photos, and variants of types.) Always to train your classifier after you have added more images. Include images that are representative of what your classifier will encounter in the real world. Photos in context are better than photos of objects in front of neutral backgrounds, for example.
- 44. Best Practices for using Custom Vision • Use at least 30 images for each tag • Images should be the focus of the picture • Use sufficiently diverse images and backgrounds (ex: cats with red background and dogs with blue background) • Train with images that are similar in {quality, resolution, lighting, etc.} to the images that will be used in prod • Supports Microsoft accounts (MSA) and AAD
- 45. Computer Vision Scenario Examples ➢ Additional Scenarios ➢ Classify user submitted images to website ➢ Identifying elements – object counting, animal identification and lots more. ➢ Hazard detection/industrial safety – adding custom rules to videos
