Image tagging, also known as image annotation, is the labeling of images to be used as AI training data. Annotated images are needed in various fields of machine learning for a variety of applications. Some of these applications include autonomous vehicles, augmented reality, and facial recognition. Instead of building a platform to annotate your own images, it is often more efficient to outsource the work from companies that provide image tagging services.
What are Image Tagging Services?
Image tagging services provide you with images annotated with your requested labels or elements. If you have your own stock of custom images, you can provide the company with the images and simply outsource the annotation work. Your images would then be given to human workers to be annotated on an existing platform or custom platform built to match your needs. Alternatively, you can request both the images and the annotation service together.
There is a wide range of image tagging services and below are ten options for outsourcing these services.
