 ### Image Analysis V4.0 Captioning and Dense Captioning (public preview):
 
-"Caption" replaces "Describe" in V4.0 as the significantly improved image captioning feature rich with details and sematic 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](./concept-describe-images-40.md).
