Implement Computer Vision
Solutions on Azure
Computer Vision covers making machines understand visual content — images and video. This part covers Azure AI Vision (Image Analysis 4.0, OCR Read API, smart cropping), the Face API, Custom Vision for training image classifiers and object detectors, and Azure AI Video Indexer with Spatial Analysis for real-time video intelligence.
Computer Vision is about teaching machines to see. Azure AI Vision (Image Analysis 4.0) analyses images for tags, objects, captions, people, and text (via the Read OCR API) — no training required. Azure Custom Vision lets you train your own image classifier or object detector using your own labelled photos. Azure AI Video Indexer extracts rich insights from video: transcripts, faces, labels, scenes, and topics. Spatial Analysis uses camera feeds to detect and track people movement in physical spaces.
Topics in this Part
Study in order — Topic 1 (Image Analysis) introduces the core Vision building blocks that Topics 2 and 3 extend.
Azure AI Vision Image Analysis 4.0 — visual features (tags, objects, captions, people, brands), the OCR Read API (async text extraction from images and PDFs), handwriting recognition, smart cropping, background removal, the Face API (detection, identification, Limited Access), and Python code with every line explained.
Training your own image classifier and object detector. Image classification vs object detection, labelling with bounding boxes, Quick vs Advanced Training, evaluation metrics (Precision, Recall, mAP, probability threshold), publishing iterations, consuming via the prediction endpoint. Includes the Custom Vision retirement warning.
Azure AI Video Indexer — indexing videos for faces, transcripts, labels, scenes, keywords, and topics. Trial vs ARM-connected account types. Querying video insights via API. Spatial Analysis with Azure Vision — detecting and tracking people in physical spaces using camera feeds, operations (PersonCount, PersonCrossingLine, PersonZoneCrossing) and edge deployment via containers.
