Hi, I’m Mohini Sultana. I’m skilled Data Annotator with 5+ years of experience in image/video labeling, AI data processing, Satellite Image Annotator, virtual assistance, and data entry. I’m reliable, deadline-driven, and ready to work across any time zone. I specialize in prioritizing tasks and solving problems efficiently to ensure high-quality results.
Common Types of Annotations:
* Bounding Boxes – Draw rectangles around objects.
* Polygon Annotation – Outline the exact shape of objects.
* Semantic Segmentation – Label every pixel in an image with a class (e.g., road, car, person).
* Instance Segmentation – Like semantic, but distinguishes between object instances
* Keypoint Annotation – Mark specific points (e.g., facial landmarks, human joints).
* Classification – Assign a label to the whole image (e.g., “cat” or “dog”).
* Object Counting – Count how many of a specific object are present.
* Lane or Line Annotation – For road detection, lane marking.
