05. Polygon

Used for irregular shapes such as special equipment, weights, machines, individual parts of the athlete’s body, and so on.

06. Semantic Segmentation

Helps annotate entire scenes from your sports data by classifying objects in the same category so the system learns to recognize them.

01. Video Annotation for Professional Sports

Video Annotation for Professional Sports

Keymakr makes use of proprietary annotation tools to label video data accurately and efficiently. Smart, scalable video annotation is the raw material for the development of exciting AI use cases for soccer and other professional sports:

  • Annotating players in each frame of video with bounding boxes allows AI models to identify and analyze their movements.
  • Deploying skeletal annotation to gain a granular understanding of how individual players move and interact.
  • Labeling product placement, badges, logos, and watermarks in each frame to measure advertising visibility and efficacy.

02. Powering Sports AI

Powering Sports AI

At Keymakr we leverage our annotation expertise and innovative labeling technology to create bespoke solutions for AI development across a range of sports:

  • Detailed and accurate annotation supports the creation of AI applications that can produce instant highlight reels for broadcasts or the internet.
  • Identify injuries before they occur with the help of skeletal annotation, or help diagnose and treat them with medical image data labeling.
  • Create detailed sports analytics models with video annotation that tracks every important event in a game.

03. Data Annotation for Fitness

Data Annotation for Fitness

Apps for home fitness and personal exercise help countless people improve both technique and performance. Keymakr collaborates with AI developers to produce a new generation of fitness products:

  • Accurate annotation supports personalized workout apps that track progress and give individuals advice on proper form.
  • Clean image and video datasets power apps that teach better technique to amateur athletes.

04. Making Fitness Mirrors Possible

Fitness Mirrors

Fitness mirrors that guide exercisers through intense and rewarding fitness programs are becoming an increasingly common feature in many homes. Accessing quality data annotation at the appropriate scales is key to ensuring this exciting technology reaches its potential:

  • Fitness mirrors can prevent injuries by alerting users when they make potentially dangerous movements.
  • Tracking of movement and the number of repetitions leads to better data that can guide users and help athletes reach their fitness goals.
