Image Analysis 4.0 Preview API deprecation

On March 31, 2025, the Image Analysis 4.0 Preview APIs will be retired. Before that date, you need to migrate your Azure Image Analysis workloads to the Image Analysis 4.0 GA API.

We encourage you to make the transition sooner to gain access to improvements such as multimodal embedding, synchronous OCR, people detection, image tagging, smart cropping, caption, dense caption, and image object detection. These Image Analysis 4.0 preview APIs will be retired on March 31, 2025:

• 2022-07-31-preview
• 2022-10-12-preview
• 2023-02-01-preview
• 2023-04-01-preview
• 2023-07-01-preview
• v4.0-preview.1

The following features will no longer be available upon retirement of the preview API versions, and they are removed from the Studio experience as of January 10, 2025:

• Model customization
• Background removal
• Product recognition

To maintain a smooth operation of your models, transition to Azure AI Custom Vision, which is now generally available. Custom Vision offers similar functionality to these retiring features.

February 2024

Multimodal embeddings GA: new multi-language model

The Multimodal embeddings API has been updated and is now generally available. The new 2024-02-01 API includes a new model that supports text search in 102 languages. The original English-only model is still available, but it can't be combined with the new model in the same search index. If you vectorized text and images using the English-only model, these vectors aren't compatible with multi-lingual text and image vectors.

See the language support page for the list of supported languages.

January 2024

New Image Analysis SDK 1.0.0-beta.1 (breaking changes)

The Image Analysis SDK was rewritten in version 1.0.0-beta.1 to better align with other Azure SDKs. All APIs have changed. See the updated quickstarts, samples and how-to-guides for information on how to use the new SDK.

Major changes:

• The SDK now calls the generally available Computer Vision REST API (2023-10-01), instead of the preview Computer Vision REST API (2023-04-01-preview).
• Support for JavaScript was added.
• C++ is no longer supported.
• Image Analysis with a custom model, and Image Segmentation (background removal) are no longer supported in the SDK, because the Computer Vision REST API (2023-10-01) doesn't yet support them. To use either feature, call the Computer Vision REST API (2023-04-01-preview) directly (using the Analyze and Segment operations respectively).

November 2023

Analyze Image 4.0 GA

The Analyze Image 4.0 REST API is now in General Availability. Follow the Analyze Image 4.0 quickstart to get started.

The other features of Image Analysis, such as model customization, background removal, and multimodal embeddings, remain in public preview.

September 2023

Deprecation of outdated Computer Vision API versions

Computer Vision API versions 1.0, 2.0, 3.0, and 3.1 will be retired on September 13, 2026. Developers won’t be able to make API calls to these APIs after that date. We recommend that all affected customers migrate their workloads to the generally available Computer Vision 3.2 API by following this QuickStart at their earliest convenience. Customers should also consider migrating to Image Analysis 4.0 API (preview), which has our latest and greatest Image Analysis capabilities.

Visit our Q&A for any questions.

May 2023

Image Analysis 4.0 Product Recognition (public preview)

The Product Recognition APIs let you analyze photos of shelves in a retail store. You can detect the presence and absence of products and get their bounding box coordinates. Use it in combination with model customization to train a model to identify your specific products. You can also compare Product Recognition results to your store's planogram document. Product Recognition.

March 2023

Azure Vision Image Analysis 4.0 SDK public preview

The Florence foundation model is now integrated into Azure Vision. The improved Vision services enable developers to create market-ready, responsible Azure Vision applications across various industries. Customers can now seamlessly digitize, analyze, and connect their data to natural language interactions, unlocking powerful insights from their image and video content to support accessibility, drive acquisition through SEO, protect users from harmful content, enhance security, and improve incident response times. For more information, see Announcing Microsoft's Florence foundation model.

Image Analysis 4.0 SDK (public preview)

Image Analysis 4.0 is now available through client library SDKs in C#, C++, and Python. This update also includes the Florence-powered image captioning and dense captioning at human parity performance.

Image Analysis V4.0 Captioning and Dense Captioning (public preview):

"Caption" replaces "Describe" in V4.0 as the improved image captioning feature rich with details and semantic understanding. Dense Captions provides more detail by generating one-sentence descriptions of up to 10 regions of the image in addition to describing the whole image. Dense Captions also returns bounding box coordinates of the described image regions. There's also a new gender-neutral parameter to allow customers to choose whether to enable probabilistic gender inference for alt-text and Seeing AI applications. Automatically deliver rich captions, accessible alt-text, SEO optimization, and intelligent photo curation to support digital content. Image captions.

Video summary and frame locator (public preview):

Search and interact with video content in the same intuitive way you think and write. Locate relevant content without the need for extra metadata. Available only in Vision Studio.

Image Analysis 4.0 model customization (public preview)

You can now create and train your own custom image classification and object detection models, using Vision Studio or the v4.0 REST APIs.

Multimodal embeddings APIs (public preview)

The Multimodal embeddings APIs, part of the Image Analysis 4.0 API, enable the vectorization of images and text queries. They let you convert images and text to coordinates in a multi-dimensional vector space. You can now search with natural language and find relevant images using vector similarity search.

Background removal APIs (public preview)

As part of the Image Analysis 4.0 API, the Background removal API lets you remove the background of an image. This operation can either output an image of the detected foreground object with a transparent background, or a grayscale alpha matte image showing the opacity of the detected foreground object.

Azure Vision 3.0 & 3.1 previews deprecation

The preview versions of Azure Vision 3.0 and 3.1 APIs are scheduled to be retired on September 30, 2023. Customers won't be able to make any calls to these APIs past this date. Customers are encouraged to migrate their workloads to the generally available (GA) 3.2 API instead. Mind the following changes when migrating from the preview versions to the 3.2 API:

• The Analyze Image and Read API calls take an optional model-version parameter that you can use to specify which AI model to use. By default, they use the latest model.
• The Analyze Image and Read API calls also return a model-version field in successful API responses. This field reports which model was used.
• Azure Vision 3.2 API uses a different error-reporting format. See the API reference documentation to learn how to adjust any error-handling code.

October 2022

Azure Vision Image Analysis 4.0 (public preview)

Image Analysis 4.0 has been released in public preview. The new API includes image captioning, image tagging, object detection, smart crops, people detection, and Read OCR functionality, all available through one Analyze Image operation.
