PRELABELING FOR SEMANTIC SEGMENTATION TASKS

One embodiment of the present invention sets forth a technique for performing a labeling task. The technique includes generating a multi-scale representation of an image as input to a machine learning model. The technique also includes performing one or more operations that apply the machine learning model to the multi-scale representation of the image to produce a semantic segmentation comprising predictions of labels for regions of pixels in the image. The technique further includes outputting, in a user interface, the semantic segmentation for use in assisting a user in specifying the labels for the pixels in the image.
