Question

You can use the __________ service to train an object detection model by using your own images.

A. Computer Vision
B. Custom Vision
C. Form Recognizer
D. Video Indexer

Answer

B. Custom Vision

Explanation

The correct answer is B. Custom Vision.

Custom Vision is a service that allows you to train an object detection model by using your own images. Object detection is a type of computer vision task that involves locating and identifying objects in an image or video. Custom Vision lets you upload your own images, label the objects you want to detect, and train a custom model using a simple web interface. You can also use Custom Vision to train an image classification model, which assigns a label to an entire image based on its content.

Computer Vision is a service that provides pre-trained models for various computer vision tasks, such as analyzing images, extracting text, generating thumbnails, and more. You can use Computer Vision to perform object detection on images, but you cannot train your own model with your own images.

Form Recognizer is a service that extracts text and data from forms, such as invoices, receipts, tax forms, and more. You can use Form Recognizer to train a custom model with your own forms, but it is not designed for object detection.

Video Indexer is a service that analyzes videos and extracts insights, such as faces, emotions, topics, keywords, transcripts, and more. You can use Video Indexer to perform object detection on videos, but you cannot train your own model with your own images.

Azure Custom Vision is a cognitive service that lets you build, deploy, and improve your own image classifiers. An image classifier is an AI service that applies labels (which represent classes) to images, according to their visual characteristics. Unlike the Computer Vision service, Custom Vision allows you to specify the labels to apply.

Note: The Custom Vision service uses a machine learning algorithm to apply labels to images. You, the developer, must submit groups of images that feature and lack the characteristics in question. You label the images yourself at the time of submission. Then the algorithm trains to this data and calculates its own accuracy by testing itself on those same images. Once the algorithm is trained, you can test, retrain, and eventually use it to classify new images according to the needs of your app. You can also export the model itself for offline use.

Incorrect Answers:
Computer Vision: Azure’s Computer Vision service provides developers with access to advanced algorithms that process images and return information based on the visual features you’re interested in. For example, Computer Vision can determine whether an image contains adult content, find specific brands or objects, or find human faces.
