Unlocking Key-points and Landmark Annotation Services

Welcome to, your trusted service provider for AI data labeling and annotation services. As a leader in the industry, we are qualified to provide insights and solutions for your data annotation needs.

What are Key-points and Landmarks?

Key-points and landmarks are specific points or locations within an image that are annotated to provide important information for various tasks, such as object detection, tracking, pose estimation, and even facial recognition. These key-points and landmarks serve as reference points to identify and analyze key features and structures within an image to help machines understand what we want them to interpret inside of their AI algorithms.

Importance of Key-point and Landmark Annotation in Machine Learning

Key-point and landmark annotations play a crucial role in machine learning. By accurately annotating key-points and landmarks, AI algorithms can understand and analyze the spatial relationships, poses, and structures of objects or subjects within images. This information is essential for applications like facial recognition, pose estimation, and human activity analysis. For example is the image of a dog, what colour, what kind, what body parts of the dog can we interpret, etc…
