Data Annotation

Semantic Segmentation Data Annotation

Semantic segmentation annotation is a specialized image labeling process where every pixel in an image is classified into a defined category. It provides the highest level of detail about object shapes and boundaries, making it essential for advanced computer vision models used in autonomous systems, medical imaging, agriculture, and retail analytics.

What Semantic Segmentation Annotation Involves

  • Pixel-level labeling that assigns each pixel to a class

  • Object outlines created with drawing tools like pen, polygon, or brush

  • Shared borders between adjacent objects to avoid overlapping masks

  • Adjusting brightness and contrast to improve visibility during annotation

  • Exportable labels ready for model training and validation datasets in deep learning workflows 

This method is more accurate than bounding boxes or object classification because it enables fine-grained recognition of every structure in an image and helps models learn precise real-world object representations.
