  Segment anything model (SAM) developed by Meta AI Research has recently
attracted significant attention. Trained on a large segmentation dataset of
over 1 billion masks, SAM is capable of segmenting any object on a certain
image. In the original SAM work, the authors turned to zero-short transfer
tasks (like edge detection) for evaluating the performance of SAM. Recently,
numerous works have attempted to investigate the performance of SAM in various
scenarios to recognize and segment objects. Moreover, numerous projects have
emerged to show the versatility of SAM as a foundation model by combining it
with other models, like Grounding DINO, Stable Diffusion, ChatGPT, etc. With
the relevant papers and projects increasing exponentially, it is challenging
for the readers to catch up with the development of SAM. To this end, this work
conducts the first yet comprehensive survey on SAM. This is an ongoing project
and we intend to update the manuscript on a regular basis. Therefore, readers
are welcome to contact us if they complete new works related to SAM so that we
can include them in our next version.
