AI-900: How to use Computer Vision to detect image color schemes

Learn how to use the Computer Vision service in Azure AI to analyze the color distribution of images and filter them by dominant foreground or background colors.

Question

You want to use the Computer Vision service with images where the dominant foreground color is red. Which of the following capabilities should you use?

A. Detect image color schemes
B. Optical character recognition
C. Detect image types

Answer

A. Detect image color schemes

Explanation

Detect image color schemes capability can identify the dominant foreground, background, and overall colors in an image.

The correct answer is A. Detect image color schemes. This capability allows you to analyze the color distribution of an image and return a summary of the dominant colors in the foreground and background. You can use this feature to filter images by color, create color-based themes, or enhance the visual appeal of your images. For example, if you want to find images where the dominant foreground color is red, you can use the Detect image color schemes capability to return the color information of each image and then select the ones that match your criteria.

The other two options are not relevant for this scenario. Optical character recognition (OCR) is used to extract printed or handwritten text from images, not colors. Detect image types is used to identify the format and encoding of an image, not the color scheme.
