I will collect pictures from my app users. How to analyze the image is safe/unsafe and to identify the type of category the content belongs to?

You can use the Catalyst Zia Image Moderation API or SDK method to identify the category of the content in the image. It recognizes inappropriate content in images and returns it in the response. The response also contains the probability of each criteria(racy, weapon, nudity, gore, drug) with their confidence scores, and the prediction of the image being safe_to_use or unsafe_to_use.
