Human Pose Estimation is a computer vision technique that utilizes Machine Learning (ML) and Deep Learning (DL) to detect, identify, and track human body poses. It is an important technology that has opened up possibilities in a variety of industries and applications. If you are a Product Manager, Entrepreneur, of Software Developer searching for “What is Human Pose Estimation?”, you have come to the right place. Read on to learn how Human Pose Estimation is now more accessible for your apps.

About us: at , we are passionate about movement through tech. We have built tools that make it easy for developers to integrate AI into their products. 

Using just the camera in a smartphone, apps can use Human Pose Estimation to create more engaging experiences.

Human Pose estimation uses machine learning algorithms to plot key points of the human body on an image or video (which is made up of multiple images). We call these key points “Landmarks”.

Apps then interpret these Human Pose Estimation Landmarks to create unique use cases, such as:

  • Identifying Poses using pose classifiers, for example a Fitness app counting reps of an exercises
  • Measuring angles between joints, for example a health app measuring range of motion for injury recovery
  • As a game controller, for example identifying the body’s position to control up, down, left, and right directions through movement, rather than a games controller

2. How Machine Learning and Deep Learning are used in Human Pose Estimation

Human Pose Estimation uses Machine Learning and Deep Learning to detect and track body poses. Machine Learning algorithms are employed to create models that can recognize various poses from a set of images or videos. Deep Learning is then used to further refine the recognition process by allowing for more detailed recognition of specific body parts, such as hands, arms, legs, and other body parts.

In addition to recognizing poses, Machine Learning and Deep Learning can also be used to create 3D models of people in real-time. This is done by analyzing the position of the human body and then rendering a 3D model for further manipulation.

4. Challenges Faced in Implementing Human Pose Estimation in a Health or Fitness App

For too long, Entrepreneurs and Software Developers faced expensive and technical challenges when implementing Human Pose Estimation into their products. These challenges prevented great ideas from being built, however, at QuickPose, we overcame these challenges so you only need a few lines of code to install our SDK. 

Time-consuming for developers

Implementing human pose estimation into an app can be a time-consuming process for developers due to several factors. One reason is that it can be challenging to design and implement algorithms that are able to accurately track and estimate the poses of people in real-time. This may require significant research and development efforts, as well as the use of sophisticated machine learning techniques.

Additionally, the implementation of human pose estimation often requires the collection and annotation of large amounts of data in order to train the algorithms. This can be a time-consuming process, as it may involve manual labeling of data by humans.

Furthermore, testing and debugging the pose estimation algorithms can also be time-consuming, as developers may need to iterate and fine-tune the algorithms in order to achieve satisfactory performance.

Finally, integrating the pose estimation functionality into the overall app architecture and user interface can also be time-consuming, as it may require careful design and planning in order to provide a seamless and intuitive user experience.

Poor accuracy:

Human Pose Estimation systems are not always 100% accurate due to the complexity of the human body, which can make it difficult for algorithms to accurately detect and track poses.

Complexity of training data:

Training a Human Pose Estimation system requires large amounts of data which can be difficult to generate or acquire.

High computational power requirements:

Human Pose Estimation systems require a lot of computational power to run, which can be expensive and time-consuming.

Privacy concerns:

Human Pose Estimation systems can collect sensitive data about individuals, which raises privacy issues that must be addressed before deploying the system in a health or fitness application.

5. Tips for Optimizing Performance with Human Pose Estimation
