Segmentation is essential for image analysis tasks.Semantic segmentationdescribes the process of associating each pixel of an image with a class label, (such asflower,person,road,sky,ocean, orcar).
Applications for semantic segmentation include:
Autonomous driving
Industrial inspection
Classification of terrain visible in satellite imagery
Medical imaging analysis
The steps for training a semantic segmentation network are as follows:
1.Analyze Training Data for Semantic Segmentation
2.Create a Semantic Segmentation Network
Large datasets enable faster and more accurate mapping to a particular input (or input aspect). Using data augmentation provides a means of leveraging limited datasets for training. Minor changes, such as translation, cropping, or transforming an image provides new distinct and unique images.

You can use theImage Labelerapp to interactively label pixels and export the label data for training. The app can also be used to label rectangular regions of interest (ROIs) and scene labels for image classification.
