Azure AI Vision Image Analysis — Python SDK Quick Reference

Condensed from azure-ai-vision-imageanalysis-py. Full patterns (dense captions, smart crops, people detection) in the azure-ai-vision-imageanalysis-py plugin skill if installed.

Install

pip install azure-ai-vision-imageanalysis

Quick Start

from azure.ai.vision.imageanalysis import ImageAnalysisClient
from azure.ai.vision.imageanalysis.models import VisualFeatures
client = ImageAnalysisClient(endpoint=endpoint, credential=credential)

Non-Obvious Patterns

analyze_from_url(image_url=..., visual_features=[...]) for URL; analyze(image_data=bytes) for file
VisualFeatures enum: CAPTION, DENSE_CAPTIONS, TAGS, OBJECTS, READ, PEOPLE, SMART_CROPS
Async: from azure.ai.vision.imageanalysis.aio import ImageAnalysisClient

Best Practices

Select only needed visual features to optimize latency and cost
Use async client for high-throughput scenarios
Handle HttpResponseError for invalid images or auth issues
Enable gender_neutral_caption for inclusive descriptions
Specify language for localized captions
Use smart_crops_aspect_ratios matching your thumbnail requirements
Cache results when analyzing the same image multiple times
