One of the most active subfields in computer vision research in recent years is object segmentation.
That’s because it’s important to accurately recognize the objects in a scene or comprehend their
location. As a result, various techniques, such as Mask R-CNN and MaskProp, have been put forth by
researchers for segmenting objects in visual situations.

For purposes ranging from scientific image analysis to the creation of aesthetic photographs,
computer vision significantly relies on segmentation, the act of identifying which pixels in an image
represents a specific item. But to create an accurate segmentation model for a specific task,
technical specialists are often required. They also need access to AI training infrastructure and
significant amounts of meticulously annotated in-domain data.

Unidentified Video Objects by Meta AI: What is it?

Unidentified Video Objects (UVO), a new benchmark to aid research on open-world segmentation, a
crucial computer vision problem that seeks to recognize, segment, and track every object in a video
thoroughly, was created. UVO can assist robots emulate humans’ ability to recognize unexpected
visual objects, whereas generally machines must acquire specific object concepts to recognize them.
A recent Meta AI study describes an initiative named “Segment Anything,” which seeks to
“democratize segmentation” by offering a new job, dataset, and model for picture segmentation.
Their Segment Anything Model (SAM) and the largest segmentation dataset ever, Segment Anything
1-Billion mask dataset (SA-1B), were developed.

Earlier there are two main categories of Segmentation

In the past, there were primarily two types of segmentation-related tactics. The first, interactive
segmentation, could segment any object, but it needs a human operator to adjust a mask. However,
predetermined item groups could be segmented thanks to automatic segmentation.

Nevertheless, training the segmentation model requires a significant number of manually labeled
items, in addition to computer power and technological know-how. Neither technique provided a
completely reliable, automatic segmentation mechanism.

Both of these more general classes of procedures are covered by SAM. It is a unified model that
carries out interactive and automated segmentation operations with ease.

By simply constructing the suitable prompt, the model can be utilized for a variety of segmentation
tasks thanks to its adaptable prompt interface. SAM is trained on a wide variety of task that are high-
quality dataset of more than 1 billion masks, which enables it to generalize to new kinds of objects
and images. Because of this capacity to generalize, practitioners will often not need to gather their
segmentation data and modify a model for their use case.

With the help of these features, SAM can switch between domains and carry out various operations.
The following are some of the SAM’s capabilities:

1. With a single mouse click or the interactive selection of inclusion and exclusion locations,
   SAM makes object segmentation easier. Another stimulus for the model is a boundary box.
2. SAM’s capacity to provide competing legitimate masks in the face of object ambiguity is a
   key characteristic of real-world segmentation issues.
3. Any object in a picture can be instantaneously detected and hidden with SAM.
4. SAM can instantaneously build a segmentation mask for any prompt after precalculating the
   picture embedding, enabling real-time interaction with the model.
   SAM allows for the rapid collection of new segmentation masks. It takes only roughly 14 seconds to
   complete an interactive mask annotation. This model is 2.5 times faster than the previous greatest
   data annotation effort, which was also model-assisted compared to previous large-scale
   segmentation data collection efforts.
   SAM is all set to empower future applications from several sectors which would require object or
   image segmentation.
