Fundamental or fundamental models of vision are used in computer vision tasks. These models serve as building blocks or initial frameworks for more complex and specific models. Researchers and developers often use them as starting points and adapt or improve them to address specific challenges or optimize them for particular applications.
Vision models are extended to video data for action recognition, video captioning, and anomaly detection in surveillance images. Their adaptability and effectiveness in handling various computer vision tasks make them an integral part of modern ai applications.
Researchers at Kyung Hee University solve problems in one such vision model called Sam (Segment any model). Their method solves two practical image segmentation challenges: segmenting anything (SegAny) and everything (SegEvery). As the name suggests, SegAny uses only a given message to segment a single element of interest in the image, while SegEvery segments all elements of the image.
SAM consists of a ViT-based image encoder and a cue-guided mask decoder. The mask decoder generates detailed masks by adopting bidirectional attention to enable efficient interaction between image encoders. SegEvery is not a requestable segmentation task, so it generates images directly through requests.
Researchers identify why SegEvery in SAM is slow and propose object-aware box messages. These cues are used in place of the default grid search point cues, significantly increasing imaging speed. They show that the fast object-ware sampling strategy is supported by distilled image encoders in MobileSAM. This will further contribute to a unified framework for efficient SegAny and SegEvery.
Their research primarily focuses on determining whether an object is located in a certain region of the image. Object detection tasks already solve this problem, but most of the generated bounding boxes overlap. Requires pre-filtering before use as a valid message to remove overlap.
The challenge with the given point message lies in the need to predict three output masks, in order to address ambiguity, which requires further mask filtering. In contrast, the box message stands out for its ability to provide more detailed information, generating higher quality masks with reduced ambiguity. This feature alleviates the requirement of predicting three masks, making it a more advantageous option for SegEvery due to its efficiency.
In conclusion, their research focuses on MobileSAMv2 and improves the speed of SegEvery by introducing an innovative fast sampling method within the signal-guided mask decoder. By replacing the conventional grid search approach with their object-aware rapid sampling technique, they noticeably improve the efficiency of SegEvery without compromising the overall performance, showing significant improvements.
