What Is Semantic Segmentation?

📰 Dev.to · Baaz

Learn about semantic segmentation, a computer-vision task that assigns class labels to pixels, and its applications

intermediate Published 4 Aug 2026
Action Steps
  1. Apply semantic segmentation to an image using a library like TensorFlow or PyTorch to assign class labels to pixels
  2. Configure a convolutional neural network (CNN) to perform semantic segmentation
  3. Test the accuracy of a semantic segmentation model using metrics like IoU (Intersection over Union)
  4. Build a dataset for semantic segmentation by annotating images with class labels
  5. Run a semantic segmentation model on a video stream to analyze and understand the content
