Are you an e-commerce company? Do you load thousands of new images regularly and want to provide good search capability to your users?
How easy would it become if your software would immediately recognize your product features as soon as an image is uploaded in your systems? Would you still want to spend days of efforts to attach the right descriptors for your product or rather make it available in a matter of minutes?
If you are still doing things manually, and still facing errors, it is time to move on to the technology of the future that is faster and offers high accuracy and reliability.
