Video data includes both image and audio aspects, so it can be used to train a wide range of machine learning models for computer vision, natural language processing, and more. You might need video training datasets as the first step for training autonomous vehicles or building a model for content moderation. For example, computer vision algorithms, such as systems that find human figures in security footage, need to be trained with carefully collected and segmented data to ensure unbiased results.

Lionbridge provides video collection, classification, and annotation services, including object localization, object detection, video tracking, and more. We provide a wide range of annotation types, including 2D and 3D bounding boxes, polygons, landmark annotation, semantic segmentation, and more. Our strict quality assurance system ensures that moving objects continue to be accounted for in all frames of your video.

We also provide video transcription services, to convert what is spoken on video into written text for subtitling or captioning. Video transcription makes your online videos more searchable and accessible because it provides a better UX and boosts SEO.
