Hello mm,

Sorry for any inconvenience caused. The character limit for captions generated by the Azure Computer Vision Image Analysis endpoint isn't explicitly stated, but the Caption feature generates a one-sentence description of the entire image content. Typically, this would be under 200-250 characters depending on the complexity of the image. For more detailed captions, the Dense Captions feature provides one-sentence descriptions of up to 10 different regions of the image, along with bounding box coordinates, but again, the length would vary based on the content.

If transparency is a concern, the caption length should generally be manageable within these limits, but you may need to test and adjust the text display according to your specific application constraints. For a quick test, you can try out the feature in Vision Studio to evaluate the output.

Could you please take a moment to retake the survey on the above response? Your feedback is greatly appreciated.
