Technologies like artificial intelligence and machine learning are being widely accepted to develop intelligent machines and applications. However, to train a machine to perform like humans, it is important to feed it with appropriate information (high-quality training datasets). This is where data annotation techniques come to play. Data annotation services is the process of labeling data and tagging it with relevant information to make the objects recognizable to the computer vision model.
