How to choose right instance segmentation model
Choosing the right segmentation model for your application depends on various factors such as the type of problem, dataset size, computational resources, and desired model performance. Here are some key steps to help you choose the appropriate segmentation model for your application:
- Define the problem: Identify the type of segmentation task your application requires: semantic segmentation, instance segmentation, or panoptic segmentation.
- Semantic segmentation: Classifying each pixel in an image to a specific class, without differentiating instances of the same class.
- Instance segmentation: Identifying each instance of an object class in an image and segmenting it from the background and other objects.
- Panoptic segmentation: Combining both semantic and instance segmentation in one unified task, aiming to assign a unique label to every pixel in an image.
- Assess dataset size and quality: Evaluate the size of your dataset and its annotation quality. A larger, high-quality dataset generally allows for more complex models to be trained effectively.
- Consider computational resources: Assess your available computational resources, such as GPU memory and processing power. Some models may require more resources than others, so choose a model that is feasible for your hardware.
- Review existing models: Research and compare existing state-of-the-art segmentation models for the specific task you are addressing. Popular models include:
- Semantic segmentation: U-Net, SegNet, DeepLabv3, PSPNet, and FCN.
- Instance segmentation: Mask R-CNN, YOLACT, and SOLO.
- Panoptic segmentation: Panoptic FPN, UPSNet, and DETR.
- Model performance: Compare the performance of different models based on the metrics relevant to your task, such as Intersection over Union (IoU), mean IoU (mIoU), or average precision (AP). Consider the trade-off between model complexity, inference speed, and accuracy.
- Adaptability and customization: Some models are more flexible and easier to adapt to new datasets or tasks. Ensure that the model you choose can be easily customized or fine-tuned to fit your specific application requirements.
- Perform experiments: Test different models on your dataset and measure their performance. Fine-tune the models as necessary, and compare their performance to choose the one that best meets your requirements.
- Evaluate inference speed: In some cases, real-time or near-real-time processing may be required. In such situations, consider models that are optimized for fast inference, such as MobileNetV2 or EfficientNet.
- Check the license: it is worth looking at the licenses of the model we are considering, because not all of them are suitable for commercial use, even if they are open-sourced. In the case of a copyleft license, the user is obliged to publish his code for free - and this closes the way for most commercial projects.
Permissive open-source licenses, allowing free use, modification, and distribution of the software with minimal restrictions. Permissive open-source licenses may differ significantly, for example: Apache License 2.0 provides an explicit grant of patent rights from contributors to users, while the MIT License does not.
Copyleft open-source license, requires that any modifications or derived works must also be released under the same AGPL-3.0 license. This enforces the open-source nature of the software, as anyone who modifies or creates derivative works must also make their changes freely available
By following these steps and considering the unique requirements of your application, you can make an informed decision about the best segmentation model to use.
