CLIPSeg: Semantic Segmentation

CLIPSeg is an open-vocabulary image segmentation model that combines the CLIP model's powerful vision-language alignment with a Transformer-based segmentation architecture. Developed by Heidelberg University, it allows users to segment objects in an image by simply providing natural language prompts like "a dog" or "the red car." CLIPSeg excels in zero-shot generalization and does not require category-specific training, making it suitable for diverse and dynamic scenarios. It is widely used in applications such as image editing, human-computer interaction, and robotics, where both language understanding and visual perception are essential.

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.
