To create the label pixel for data images which can be used for semantic segmentation using deep learning, you can use ‘Image Labeler’ app as it is an easy way to interactively create a variety of shapes to mark as region of interest (ROI) labels. You can create axis-aligned or rotated rectangular, polyline, pixel, and polygon ROI labels and scene labels in an image or image sequence.
For pixel label, draw pixels to label various classes, such as road or sky, for semantic segmentation. Select the ‘Superpixel’ tool from the toolstrip to create a super pixel grid layout over an image. Select a predefined pixel label definition and then left-click a grid to assign the selected pixel label definition to it. You can remove the labels from ‘superpixel’ grid using the Erase tool to the right of the ‘Superpixel’ tool.
