Video Annotation Services
Video annotation is complex: it involves labeling sequences of images (frames) and often tracking objects or actions across time. Our expert team has developed sophisticated workflows to transform raw video into richly annotated training data.
Object Tracking Across Frames
We annotate objects (e.g., people, vehicles, animals) in each frame and maintain persistent IDs so they are tracked throughout the video. This results in a trajectory for each object. Whether it's a pedestrian crossing a street in a traffic video or a soccer player moving across the field, our annotators ensure the object is consistently labeled from start to finish.
We employ advanced techniques like interpolation to speed up the process while a human validates key frames – ensuring both efficiency and accuracy.
Event & Activity Recognition
Beyond objects, we can label actions or events in videos. For example, in security footage we might tag segments where "someone falls down" or in sports footage label "goal scored" moments. We work with domain-specific taxonomies (like a set of sport-specific actions) to tag the presence of those events in time.
This training data is essential for AI models that need to detect what is happening, not just who or what is present.
Keypoint and Pose Annotation
For applications like pose estimation or gesture recognition, we annotate keypoints on the human body (or other articulated objects) in videos. This means frame by frame marking of joints (ankles, knees, wrists, etc.) or facial landmarks, so that the model learns how those points move over time.
Our specialized team can label these with precision, enabling datasets for understanding human motion and gestures with framewise temporal consistency.
Polygon/Segmentation in Video
In cases like drone or satellite video analysis, we perform segmentation on each frame (e.g., outline the boundaries of a wildfire in aerial footage frame-by-frame to see how it spreads, or segment different land types). We ensure consistency of segmentation labels across frames.
It's challenging, but we have proprietary processes to propagate annotations and carefully adjust them as needed in subsequent frames, maintaining pixel-perfect precision.
Applications & Industries
Our premium video annotation services power cutting-edge AI applications across multiple sectors. By delivering precisely labeled video data, we help organizations build intelligent systems that can understand and interpret visual information with human-like accuracy.
Autonomous Driving & ADAS
Perhaps the most demanding use of video annotation. Self-driving cars use cameras and annotated video to learn to navigate. We label traffic videos capturing complex scenarios: cars merging, pedestrians jaywalking, cyclists, traffic light changes, etc. A 50% growth in demand for video annotation services is largely due to this sector.
YPAI has significant experience in autonomous vehicle datasets – providing both 2D video and synced 3D sensor annotations.
Surveillance & Security
Whether for smart city initiatives or private security firms, analyzing CCTV footage with AI is growing. We annotate security videos to identify intrusions, detect accidents, or track persons of interest. For example, we can tag instances of trespassing, or follow a subject across multiple camera views.
This data helps train models for automated security monitoring and anomaly detection.
Sports Analytics
In sports, video is king. We annotate player movements, ball trajectory, and important actions (passes, shots, goals) in sports footage. Sports tech companies use these labels to build models that generate statistics or automate highlight reels.
Our accuracy in tracking fast-moving objects (like a ball) and players means AI can reliably analyze game play.
Drones & Aerial Video
From agriculture (monitoring crop growth via drone video) to disaster response (assessing damage via aerial footage), we label objects and regions in overhead videos. This might involve tracking herds of animals for wildlife conservation, or counting cars from drone traffic monitoring.
Our team adapts to the unique viewpoint and scale of aerial imagery for accurate annotations.
Entertainment & AR/VR
In augmented reality and VR, understanding the real-time video feed is crucial (for overlaying graphics, etc.). We provide labeled video data to train these systems – such as segmenting surfaces/walls, or identifying people and their poses for AR effects.
Video annotation assists in VFX and post-production automation by training AI to detect scene elements.
Manufacturing & Industrial
Video annotation enables advanced quality control and automation in manufacturing. We annotate production line footage to help AI systems detect defects, monitor equipment, and ensure workplace safety compliance.
Our industrial video annotation handles challenging factory environments with variable lighting, complex machinery, and fast-moving assembly lines.
Healthcare & Medical
Medical video analysis is transforming diagnostics and treatment. We annotate surgical videos, endoscopy footage, and patient monitoring data to train AI systems that can identify anomalies, track surgical tools, or monitor patient movements.
Our medical video annotation meets strict accuracy requirements while maintaining patient privacy and complying with healthcare regulations.
Retail & Consumer Analytics
Retail video annotation helps businesses understand customer behavior and optimize store layouts. We annotate in-store footage to track shopper journeys, analyze product interactions, and monitor checkout efficiency.
Our retail annotations enable heat mapping, dwell time analysis, and demographic insights while maintaining customer privacy.
Education & E-Learning
Video annotation is revolutionizing educational content and online learning experiences. Our specialized team annotates instructional videos to track presenter gestures, highlight key concepts, and identify effective teaching patterns that help AI systems customize learning experiences.
By precisely labeling teaching sequences and student interactions, we enable the development of intelligent tutoring systems that can analyze learner engagement in real-time and adapt teaching methods accordingly.
Our education-focused annotation services integrate with leading e-learning platforms to create adaptive learning paths that respond to individual student needs, improving knowledge retention and educational outcomes.
Why Choose YPAI for Video Annotation?
Efficiency without Compromise
Annotating video can be time-consuming, but we pride ourselves on efficiency. By using smart interpolation and tracking tools, we reduce manual effort while our annotators oversee for quality. This hybrid approach means we can deliver video projects faster than many competitors, who might rely on either fully manual (slow) or overly automated (error-prone) methods. We find the sweet spot.
Quality Control at Scale
We implement hierarchical QC for video. For example, a lead reviewer might watch random segments of annotated video to ensure objects are consistently tracked (no ID switch errors, no missed frames). We also use metrics like MOTA (Multiple Object Tracking Accuracy) to quantitatively assess our work on sample sequences. Clients have visibility into QA results – we often provide short sample videos with annotations visualized, so you can see the quality for yourself.
Tooling Expertise
YPAI is experienced with industry-standard video annotation tools (e.g., CVAT, V7 Darwin, Labelbox video, etc.). We can also work with custom tooling. We ensure that things like frame rate handling, keyframe marking, and interpolation settings are tuned for your project. If needed, we can even script certain repetitive tasks (for instance, if a video has many frames of static scene, we can automate carry-over of annotations, saving time and cost).
Handling Volume & Length
Whether it's hundreds of 10-second clips from a lab or continuous hours of driving footage, we can handle it. We organize annotation tasks in parallel among our team to tackle large volumes efficiently. Our project managers break down long videos into manageable chunks, ensuring consistency by having the same annotator handle overlapping segments where continuity matters. We also communicate with clients to define priorities (maybe you need certain critical videos first for an upcoming model training milestone – we are agile in our delivery scheduling).
Cost-Effective Solutions
Given the effort involved, video annotation can be pricey. However, YPAI strives to be cost-effective by leveraging our global workforce and optimized process. We offer transparent pricing models – per frame, per minute of video, or per object – whichever aligns best with client needs. And because our quality reduces the need for re-annotation or extensive post-processing, you save costs in the long run by doing it right the first time.
