Metadata adjustments are captured in a complex type created for each image. For images that have metadata on orientation, image rotation is adjusted for vertical loading.Large images are resized to a maximum height and width to make them uniform and consumable during skillset processing.Image normalization includes the following operations: As a developer, you enable image normalization by setting the "imageAction" parameter in indexer configuration. This second step occurs automatically and is internal to indexer processing. Image processing requires image normalization to make images more uniform for downstream processing. Extracted text is queued for text processing, if applicable. Enhancement of the extracted text components is required because the. Extracted images are queued for image processing. Text extraction is the stage where the text components are segmented from the background.

If you're using a full access connection string that includes a key, the key gives you permission to the content. There are three main tasks related to retrieving images from a blob container:Įnable access to content in the container. If there are more than 1000 images in a document, the first 1000 will be extracted and a warning will be generated.Īzure Blob Storage is the most frequently used storage for image processing in Cognitive Search. A maximum of 1000 images will be extracted from a given document. Images are either standalone binary files or embedded in documents (PDF, RTF, and Microsoft application files).
