Semantic Segmentation

Semantic image segmentation

Semantic segmentation associates each pixel of an image with a class label, such as flower, person, road, sky, or car. Use the Image Labeler and the Video Labeler apps to interactively label pixels and export the label data for training a neural network.

Input image of a seascape, then a series of cubes representing a deep learning network and a semantic segmented output image of the input.

Apps

Image LabelerLabel images for computer vision applications
Video LabelerLabel video for computer vision applications
