Techniques for semantic segmentation of images are presented. The techniques include obtaining a semantic segmentation model, the semantic segmentation model having been trained using a first subset of sliding windows and corresponding first ground truth masks for the first subset of sliding windows; ranking a plurality of sliding windows from a corpus of training images according to an uncertainty metric; selecting a next subset of sliding windows from the corpus of training images based on the ranking and based on a similarity metric for one or more characteristics of a sliding window relative to other sliding windows; providing a collaborative user interface; receiving ground truth masks for the next subset of sliding windows using the collaborative user interface; and retraining the semantic segmentation model using the next subset of sliding windows and the ground truth masks for the next subset of sliding windows.
