PoseNet-MobileNet is a lightweight human pose estimation model that combines the PoseNet algorithm with the MobileNet backbone, designed for efficient real-time keypoint detection on mobile and edge devices. The model can predict the positions of human body keypoints such as the head, shoulders, elbows, and knees, and is suitable for both single-person and multi-person pose estimation tasks. Leveraging MobileNet’s efficient feature extraction, PoseNet-MobileNet achieves a good balance between accuracy and speed with low computational cost. It is widely used in applications such as fitness tracking, augmented reality, and human-computer interaction.

When the user has fine-tuned the source model, the model conversion process must be performed again.

Users can refer to either of the following two methods to complete the model conversion:

• Using AIMO for model conversion: Click Model Conversion Reference in the Performance Reference section on the right to view the conversion steps.

• Using Qualcomm QNN for model conversion: Please refer to the Qualcomm QNN Documentation.

The model performance benchmarks and example code provided by Model Farm are all implemented based on the APLUX AidLite SDK.

For models in .bin format, you can use either of the following two inference engines to run inference on Qualcomm chips:

Inference using APLUX AidLite: please refer to the APLUX AidLite Developer Documentation

Inference using Qualcomm QNN: Please refer to the Qualcomm QNN Documentation

Inference Example Code

The inference example code is implemented using the AidLite SDK.
