(DataFlex) Google Vision Web DetectionSee more Google Vision ExamplesDemonstrates how to use the Cloud Cloud Vision API for the Web Detection method.The Google Cloud Vision "web detection" API call performs web detection analysis on an image. When you send an image to the Vision API with the "web detection" feature enabled, the API returns information about web entities (objects, logos, landmarks, etc.) that are visually similar to objects in the image and are found on the web. It includes:
Overall, the web detection feature of the Google Cloud Vision API allows you to perform reverse image search-like functionality, identifying objects in an image and providing information about similar objects found on the web. This can be useful for tasks such as image classification, content moderation, and visual search applications. Note: This example requires Chilkat v11.0.0 or greater.
