WeDetect: Optimized for Qualcomm Devices

WeDetect is a text-conditioned object detection model that uses a prompt-then-detect strategy. Text class names are reparameterized into the model weights before export, producing a fixed-vocabulary detector that runs efficiently on-device. The model uses LTRB (Left-Top-Right-Bottom) regression with multi-scale feature maps at strides 8, 16, and 32.

This is based on the implementation of WeDetect found here. This repository contains pre-exported model files optimized for Qualcomm® devices. You can use the Qualcomm® AI Hub Models library to export with custom configurations. More details on model performance across various devices, can be found here.

Qualcomm AI Hub Models uses Qualcomm AI Hub Workbench to compile, profile, and evaluate this model. Sign up to run these models on a hosted Qualcomm® device.

Getting Started

Due to licensing restrictions, we cannot distribute pre-exported model assets for this model. Use the Qualcomm® AI Hub Models Python library to compile and export the model with your own:

  • Custom weights (e.g., fine-tuned checkpoints)
  • Custom input shapes
  • Target device and runtime configurations

See our repository for WeDetect on GitHub for usage instructions.
