Meet FastSAM: the innovative real-time solution that achieves high-performance segmentation with minimal computational load

The Segment Anything Model (SAM) is a newer proposal in the field. It’s a basic vision concept that has been hailed as a breakthrough. You can employ multiple possible user engagement prompts to accurately segment any object in the image. Using a Transformer model that has been extensively trained on the SA-1B dataset, SAM can easily handle a wide variety of situations and objects. In other words, Segment Anything is now possible thanks to SAM. This task has the potential to serve as the foundation for a wide variety of future visioning challenges due to its generalizability.

Despite these improvements and the promising results of SAM and subsequent models in handling any segment task, there is still a need to improve their practical implementations. The main challenge with the SAM architecture is the high processing requirements of the transformer models (ViT) in contrast to their convolutional analogues. The increase in demand for business applications inspired a team of researchers in China to create a real-time response to any segment problem; the researchers call it FastSAM.

To solve this problem, the researchers divided the task of targeting anything into two parts: targeting all instances and request-driven selection. The first step depends on using a detector based on a Convolutional Neural Network (CNN). Segmentation masks are generated for each instance of the image. The second stage then displays the matching region of interest for the input. They show that a real-time model for any arbitrary data segment is feasible using the computational efficiency of convolutional neural networks (CNNs). They also believe that our approach could pave the way for widespread use of the fundamental segmentation process in retail settings.

Using the YOLACT approach, YOLOv8-seg is an object detector that forms the basis of our proposed FastSAM. The researchers also use SAM’s comprehensive SA-1B dataset. This CNN detector achieves performance on par with SAM despite being directly trained using only 2% (1/50) of the SA-1B dataset, allowing real-time application despite limitations of resources and computational significantly reduced. They also demonstrate its generalization performance by applying it to various downstream segmentation tasks.

The segment-anything-in-real-time model has practical applications in industry. It has a wide range of possible uses. The suggested method not only offers a novel and implementable answer for a wide variety of vision tasks, but also at a very high speed, often tens or hundreds of times faster than conventional approaches. The new insights it provides on the architecture of large models for general vision problems are also welcome. Our research suggests that there are still cases where specialized models offer the best balance between efficiency and precision. Our method then demonstrates the feasibility of a path that, by inserting an artificial before the structure, can greatly minimize the computational cost required to run the model.

The team summarizes its main contributions as follows:

• The Segment Anything challenge is addressed by introducing a revolutionary real-time CNN-based method that dramatically reduces processing requirements without sacrificing performance.
• This article provides insight into the potential of lightweight CNN models in challenging viewing tasks, including the first investigation of the application of a CNN detector to any challenge segment.
• The merits and shortcomings of the suggested method in any domain segment are revealed through a comparison with SAM on various benchmarks.

Overall, the proposed FastSAM matches the performance of SAM and is 50x and 170x faster to run, respectively. Its fast performance could benefit industrial applications such as road obstacle identification, video instance tracking, and image editing. FastSAM can produce higher quality masks for large objects in some photos. The suggested FastSAM can fulfill the real-time segment operation by selecting robust and efficient objects of interest from a segmented image. They conducted empirical research comparing FastSAM to SAM on four zero-shot tasks: edge recognition, proposal generation, instance segmentation, and text prompt localization. The results show that FastSAM is 50 times faster than SAM-ViT-H at runtime and can efficiently process many downstream jobs in real time.
