SERVICES

2D Image Annotation Solutions

Sama delivers best-in-class video annotation services for the most complex and demanding machine learning models.

Detect and define the location of your target objects. Our video annotation experts use bounding boxes to accurately segment videos used for a variety of applications including autonomous driving, food system optimization, and more. Bounding boxes are best used for object tracking and object detection.

  • Achieve accurate placement with just two clicks with crosshair lines
  • Use state tracking for occlusion, truncation and overlapping objects
  • Create custom classes, multiple attributes per instance, and hierarchical relationships
  • Power up your object tracking with ML Assist for faster high-quality annotations
  • Use ML-assisted or linear interpolation between frames

Localize and detect complex objects with precision.

Polygons are used as part of our video annotation solutions to improve the accuracy of object detection algorithms. They are best used for applications when a more precise definition of an object’s boundaries are needed such as vehicle detection, crop identification and more.

  • Apply ML-assisted annotation for polygon for auto-annotation
  • Use grouping and layering for similar objects
  • Engage quick editing tools for adding and removing points
  • Create custom classes, multiple attributes per instance, and hierarchical relationships
  • Utilize linear interpolation between frames

polygons

Easily detect and annotate pose variations.

Keypoints are a video annotation technique that our team uses to capture the location and orientation of landmarks within a video. Keypoints are best for motion tracking, facial landmark detection and hand gesture recognition as they track the movement of individual objects.

  • Configure any custom keypoint shape including skeletons, hands, and eyes in a repeatable pattern for consistent results
  • Landmark important features using points
  • Get support for custom classes, multiple attributes per instance, and hierarchical relationships
  • Utilize linear interpolation between frames

Annotate straight or curved objects with precision.

Lines and arrows are used in 2D video annotation to highlight important features in a video for object tracking or scene understanding. This is useful for understanding things like lane marking and traffic patterns or identifying buildings in a city.

  • Outline object boundaries with lines for clear edge identification
  • Highlight directional indicators with arrows
  • Get support for custom classes, multiple attributes per instance, and hierarchical relationships
  • Utilize linear interpolation between frames

line arrows

Detect the depth and height of your object of interest for vehicle and pedestrian identification, robotic movement, and interior furniture placement.

  • Apply cuboids in both 2D & 3D for a variety of mixed applications
  • Enable highly accurate 2D cuboids in just three clicks via our multi-click technology
  • Get support for custom classes, multiple attributes per instance, and hierarchical relationships
  • Utilize linear interpolation between frames

USE CASES

Image Annotation Use Cases

Sama’s image annotation experts improve ML model performance by delivering annotations with unmatched accuracy and speed.

vehicle detection

Lane Identification

Sama experts deploy polyline annotation to produce training data that instruct machine learning models to recognize specific space parameters in which they operate.

kickboxing

Pose

Annotators connect the dots across the human body to establish a relationship between points, like from shoulder to elbow to wrist. This helps models recognize human postures and movements, which is of particular value to AR/VR applications.

object detection

Scene Segmentation

Our team segments images into individual pixels so that every single pixel in an image is categorized into a class. Because of the extremely high level of detail captured by scene segmentation, it is of most value to high-risk and high-value use cases.

furniture and objects detection

Instance Segmentation

Instance segmentation is an advanced image annotation technique. A combination of object detection and semantic segmentation, objects are classified by more than one category, while also identified as unique objects. The layering of more fine-grained details improves object recognition.

vehicle detection

Scene Categorization

Categorization provides environmental or other context for specific scenes in order to train models to identify and classify images.

PROCESS

2D Video Annotation Process

Sama’s video annotation projects start with tailored consultations, assessing tagging needs via knowledgeable solutions engineers. After evaluating alternatives, projects launch on Sama’s cutting-edge video annotation platform.

callibration

For our video annotation services, we employ an integrated calibration process to maximize efficiency and value. In the initial session, we establish clear instructions, address edge cases, and align on key metrics. Subsequent collaborative meetings with a project manager, solutions engineer, and QA agent, whether weekly or monthly, ensure quality scaling as you utilize our services.

callibration

Each project is assigned to a dedicated team at Sama, consisting of internal experts with deep industry knowledge – avoiding consultants, contractors, or crowdsourcing. These teams undergo project-specific training, ensuring their effectiveness from the outset. This methodology extends to our video annotation services, where specialized training empowers our teams to excel in handling video training data right from the start.

training

Sama continually enhances its video annotation solutions through iterative feedback, with a focus on shaping and refining annotations using a video annotation tool. We utilize level feedback, percentage of data set review, and automated scoring, bolstered by real-time analytics that offer immediate actionable insights. Should data accuracy not meet client expectations, we provide complimentary rework services for the project.

review

Sama’s video annotation services offer flexible and customizable delivery formats for key metric reports and evaluations within its image annotation service. This is complemented by robust quality control measures to reduce inaccuracies swiftly, ensuring the rapid deployment of ML models.
