Find Similar Images Introduction This article explains how to find similar images. First, you will upload a group of images to Cloud Storage then use the API to find similar images.
The API URL is: GET /imaging/ai/imageSearch/{searchContextId}/findSimilar
Resource URI Swagger UI lets you call Aspose.Imaging REST APIs directly from the browser. The description of the APIs and their parameters are also given there.

SDKs Using an SDK (API client) is the quickest way for a developer to speed up the development. An SDK takes care of a lot of low-level details of making requests and handling responses and lets you focus on writing code specific to your particular project. Check out our GitHub repository for a complete list of Aspose.Imaging SDKs along with working examples, to get you started in no time.
