This task is designed to segment any object within an image based on various possible user interaction prompts. The model performs competitively despite significantly reduced computation, making it a practical choice for a variety of vision tasks. This is based on the implementation of FastSam-S found [here](https://github.com/CASIA-LMC-Lab/FastSAM). This repository contains pre-exported model files optimized for Qualcomm® devices. You can use the [Qualcomm® AI Hub Models](https://github.com/qualcomm/ai-hub-models/blob/main/src/qai_hub_models/models/fastsam_s) library to export with custom configurations. More details on model performance across various devices, can be found [here](#performance-summary). Qualcomm AI Hub Models uses [Qualcomm AI Hub Workbench](https://workbench.aihub.qualcomm.com) to compile, profile, and evaluate this model. [Sign up](https://myaccount.qualcomm.com/signup) to run these models on a hosted Qualcomm® device. ## Getting Started There are two ways to deploy this model on your device: ### Option 1: Download Pre-Exported Models Below are pre-exported model assets ready for deployment. | Runtime | Precision | Chipset | SDK Versions | Download | |---|---|---|---|---| | ONNX | float | Universal | QAIRT 2.42, ONNX Runtime 1.24.3 | [Download](https://qaihub-public-assets.s3.us-west-2.amazonaws.com/qai-hub-models/models/fastsam_s/releases/v0.52.0/fastsam_s-onnx-float.zip) | QNN_DLC | float | Universal | QAIRT 2.45 | [Download](https://qaihub-public-assets.s3.us-west-2.amazonaws.com/qai-hub-models/models/fastsam_s/releases/v0.52.0/fastsam_s-qnn_dlc-float.zip) | TFLITE | float | Universal | QAIRT 2.45 | [Download](https://qaihub-public-assets.s3.us-west-2.amazonaws.com/qai-hub-models/models/fastsam_s/releases/v0.52.0/fastsam_s-tflite-float.zip) For more device-specific assets and performance metrics, visit **[FastSam-S on Qualcomm® AI Hub](https://aihub.qualcomm.com/models/fastsam_s)**. ### Option 2: Export with Custom Configurations Use the [Qualcomm® AI Hub Models](https://github.com/qualcomm/ai-hub-models/blob/main/src/qai_hub_models/models/fastsam_s) 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 This option is ideal if you need to customize the model beyond the default configuration provided here. See our repository for [FastSam-S on GitHub](https://github.com/qualcomm/ai-hub-models/blob/main/src/qai_hub_models/models/fastsam_s) for usage instructions. ## Model Details **Model Type:** Model_use_case.semantic_segmentation **Model Stats:** - Model checkpoint: fastsam-s.pt - Inference latency: RealTime - Input resolution: 640x640 - Number of parameters: 11.8M - Model size (float): 45.1 MB ## Performance Summary | Model | Runtime | Precision | Chipset | Inference Time (ms) | Peak Memory Range (MB) | Primary Compute Unit |---|---|---|---|---|---|--- | FastSam-S | ONNX | float | Snapdragon® 8 Elite Gen 5 Mobile | 3.356 ms | 0 - 211 MB | NPU | FastSam-S | ONNX | float | Snapdragon® X2 Elite | 4.364 ms | 20 - 20 MB | NPU | FastSam-S | ONNX | float | Snapdragon® X Elite | 8.624 ms | 19 - 19 MB | NPU | FastSam-S | ONNX | float | Snapdragon® 8 Gen 3 Mobile | 5.978 ms | 15 - 284 MB | NPU | FastSam-S | ONNX | float | Qualcomm® QCS8550 (Proxy) | 8.007 ms | 0 - 26 MB | NPU | FastSam-S | ONNX | float | Qualcomm® QCS9075 | 12.805 ms | 12 - 15 MB | NPU | FastSam-S | ONNX | float | Snapdragon® 8 Elite For Galaxy Mobile | 4.486 ms | 11 - 236 MB | NPU | FastSam-S | QNN_DLC | float | Snapdragon® 8 Elite Gen 5 Mobile | 3.136 ms | 4 - 195 MB | NPU | FastSam-S | QNN_DLC | float | Snapdragon® X2 Elite | 8.058 ms | 5 - 5 MB | NPU | FastSam-S | QNN_DLC | float | Snapdragon® X Elite | 8.236 ms | 5 - 5 MB | NPU | FastSam-S | QNN_DLC | float | Snapdragon® 8 Gen 3 Mobile | 5.846 ms | 0 - 212 MB | NPU | FastSam-S | QNN_DLC | float | Qualcomm® QCS8275 (Proxy) | 39.198 ms | 1 - 186 MB | NPU | FastSam-S | QNN_DLC | float | Qualcomm® QCS8550 (Proxy) | 7.628 ms | 5 - 42 MB | NPU | FastSam-S | QNN_DLC | float | Qualcomm® SA8775P | 11.608 ms | 1 - 183 MB | NPU | FastSam-S | QNN_DLC | float | Qualcomm® QCS9075 | 10.938 ms | 5 - 15 MB | NPU | FastSam-S | QNN_DLC | float | Qualcomm® QCS8450 (Proxy) | 16.035 ms | 5 - 213 MB | NPU | FastSam-S | QNN_DLC | float | Qualcomm® SA7255P | 39.198 ms | 1 - 186 MB | NPU | FastSam-S | QNN_DLC | float | Qualcomm® SA8295P | 13.786 ms | 0 - 178 MB | NPU | FastSam-S | QNN_DLC | float | Snapdragon® 8 Elite For Galaxy Mobile | 4.491 ms | 5 - 196 MB | NPU | FastSam-S | TFLITE | float | Snapdragon® 8 Elite Gen 5 Mobile | 3.007 ms | 0 - 98 MB | NPU | FastSam-S | TFLITE | float | Snapdragon® 8 Gen 3 Mobile | 5.171 ms | 0 - 113 MB | NPU | FastSam-S | TFLITE | float | Qualcomm® QCS8275 (Proxy) | 37.806 ms | 4 - 85 MB | NPU | FastSam-S | TFLITE | float | Qualcomm® QCS8550 (Proxy) | 6.943 ms | 4 - 21 MB | NPU | FastSam-S | TFLITE | float | Qualcomm® SA8775P | 10.722 ms | 4 - 90 MB | NPU | FastSam-S | TFLITE | float | Qualcomm® QCS9075 | 10.692 ms | 3 - 38 MB | NPU | FastSam-S | TFLITE | float | Qualcomm® QCS8450 (Proxy) | 14.092 ms | 4 - 232 MB | NPU | FastSam-S | TFLITE | float | Qualcomm® SA7255P | 37.806 ms | 4 - 85 MB | NPU | FastSam-S | TFLITE | float | Qualcomm® SA8295P | 13.085 ms | 4 - 195 MB | NPU | FastSam-S | TFLITE | float | Snapdragon® 8 Elite For Galaxy Mobile | 3.966 ms | 4 - 104 MB | NPU ## License * The license for the original implementation of FastSam-S can be found [here](https://github.com/CASIA-LMC-Lab/FastSAM/blob/main/LICENSE). ## References * [Fast Segment Anything](https://arxiv.org/abs/2306.12156) * [Source Model Implementation](https://github.com/CASIA-LMC-Lab/FastSAM) ## Community * Join [our AI Hub Slack community](https://aihub.qualcomm.com/community/slack) to collaborate, post questions and learn more about on-device AI. * For questions or feedback please [reach out to us](mailto:ai-hub-support@qti.qualcomm.com).
