Keypoint Detection

Detect keypoints in objects using convolutional neural networks (CNNs)

Keypoint detection, also known as keypoint localization or landmark detection, is a computer vision task that involves identifying and localizing specific points of interest in an image. In computer vision tasks, keypoints represent human body joints, facial landmarks, or salient points on objects.

Keypoint detection provides essential information about the location, pose, and structure of objects or entities within an image, playing a critical role in computer vision applications such as these.

  • Pose estimation

  • Object detection and tracking

  • Facial analysis

  • Augmented reality

Keypoint detection on a group of people

Deep learning-based approaches to keypoint detection in objects use convolutional neural networks (CNNs), such as a high resolution deep learning network (HRNet). You can train a custom object keypoint detector, or use transfer learning to modify a pretrained keypoint detector and fine-tune it for your application. For more information on transfer learning, see Deep Learning: Transfer Learning in 10 lines of MATLAB Code.

Convolutional neural networks require a Deep Learning Toolbox™ license. You can perform GPU-based training and prediction on a CUDA®-capable GPU. Use of a GPU is recommended and requires a Parallel Computing Toolbox™ license. For more information, see Preferenze Computer Vision Toolbox and Parallel Computing Support in MathWorks Products (Parallel Computing Toolbox).
