In a recent study titled "Can SAM Count Anything? An Empirical Study on SAM Counting," authors Zhiheng Ma, Xiaopeng Hong, and Qinnan Shangguan explore the capabilities of the Segment Anything model (SAM) developed by Meta AI. SAM has gained attention for its impressive performance in class-agnostic segmenting. The researchers specifically investigate SAM's potential for few-shot object counting, which involves counting objects of an unseen category by providing a few bounding boxes as examples. The study compares SAM's performance with other existing few-shot counting methods. The findings reveal that SAM's current performance is unsatisfactory without further fine-tuning, especially when it comes to small and crowded objects. This suggests that additional adjustments and refinements are necessary to improve its accuracy in these challenging scenarios. For those interested in exploring the code related to this research, it can be accessed at \url{https://github.com/Vision-Intelligence-and-Robots-Group/count-anything}. Overall, this empirical study sheds light on the limitations of SAM for few-shot object counting and highlights the need for further development in order to enhance its effectiveness in handling various object types and densities.

Abstract: Meta AI recently released the Segment Anything model (SAM), which has garnered attention due to its impressive performance in class-agnostic segmenting. In this study, we explore the use of SAM for the challenging task of few-shot object counting, which involves counting objects of an unseen category by providing a few bounding boxes of examples. We compare SAM's performance with other few-shot counting methods and find that it is currently unsatisfactory without further fine-tuning, particularly for small and crowded objects.
