Mask2Former: Semantic Segmentation

Mask2Former, proposed by Meta AI in 2022, is a unified framework for image segmentation (instance, semantic, and panoptic). It leverages a Transformer decoder with learnable "mask queries" to dynamically generate segmentation masks, eliminating dependency on anchors or proposals. The model integrates multi-scale feature enhancement, combining high-resolution details with deep semantics, and optimizes query-feature interaction via cross-attention. Achieving state-of-the-art results on COCO and ADE20K, Mask2Former excels in complex scenes and small-object segmentation. Its end-to-end architecture supports flexible deployment in autonomous driving, medical imaging, and remote sensing, advancing unified high-performance segmentation solutions.

Model Optimization

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.

Model Inference

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.
