A Comprehensive Range of Video Annotation Services for AI and ML

The primary aim of video annotation is to make AI models detect the objects in the videos. Our team works toward outlining the objects of interest frame-by-frame using various annotating techniques.

Video Tagging using 2D and 3D Bounding Boxes Annotation

Our video tagging specialists use 2D bounding box & 3D cuboid annotation techniques to label objects in motion in a video. These labeled objects become the training data sets that enable your computer vision models to detect the object's depth, volume, and distance.

Adapting to our client's requirements, we employ the right annotation tools and expertise to annotate objects. For instance, we create datasets to help autonomous vehicles like cars recognize signboards, pedestrians, vehicles, traffic lights, signals, etc., in real-world scenarios.

2D-3D Bounding boxes

Video Labeling using Polygons

Computer vision-based machines cannot detect coarse and irregular-shaped objects on the street without video labeling. Such challenges can be marked successfully using the polygon annotation technique.

At SunTec.AI, we deploy the polygon annotation technique to plot points on the object vertices and determine their exact edges to facilitate precise localization. This is widely used in the automotive sector to annotate moving objects on the road.

Vidoe Annotation Polygon

Landmark Annotation

Our annotators create dots for the images in a video and build the structure of the required objects by connecting and linking the dots.

Our landmark video annotation services help prepare high-quality, accurate training data for your computer vision models, which helps them recognize human emotions and expressions, activities, movements, and poses accurately. Our reliable, efficient, state-of-the-art facility provides landmark annotation over multiple frames for various applications. We ensure accurate tagging of structural points in frames of interest in your data.

Video Landmark Annotation

Annotate Video with Semantic Segmentation

SunTec.AI offers pixel-based semantic segmentation of objects in each video frame. We partition the video frames into multiple segments to help AI models closely detect individual parts in real time. This technique is essential when training data requires excellent granularity for precise object recognition.

This method works best in scenarios requiring a more systematic entity labeling approach. Our team defines linear structures within video data to help machine-powered models trace the shape of pipelines, rails, road markings, lanes, and more. This kind of annotation is also used where a particular region needs to be annotated as a boundary.

Delivering Tailored Video Annotation Solutions to Businesses Globally

Video Annotation Process

As a trusted video annotation service provider, we follow a methodological approach to annotate objects in motion and deliver intended outcomes within a short turnaround time. Here are the steps we follow to annotate video adeptly:

  • Analyze Your Requirements

    Once you share your requirements with our experts, they implement a solution-based approach to create a plan of action and achieve desired results.

  • Annotate Videos

    After understanding your project requirements, our annotators employ state-of-the-art techniques and tools to create high-quality training data sets. Our team ensures the training data aligns with your needs and goals.

  • Quality Check

    The annotated data is sent to our quality experts to conduct a rigorous quality check to verify whether the data sets produced are correct and meet the set standards. If data sets do not clear the quality check, they are sent for rework.

  • Project Delivery

    If the video annotation results clear the quality check, the project is delivered to the client. We can share the data sets as an email attachment or directly upload them to your preferred server.

  • Feedback

    You can analyze whether the data sets meet your requirements. If unsatisfied with the results, you can contact our experts and ask for revisions. We serve our customers until they get the desired results.
