We have recently added models for edge detection, that can be used for extracting residential and agricultural parcels, a state-of-the-art model for road extraction, as well as models for change detection, and for image translation, both from other images, as well as from images to text, i.e. image captioning.<\/p>\n

3D Deep Learning<\/strong><\/p>\n

Deep learning often needs a lot of training data. For smaller datasets, machine learning can often provide the answer without needing as much computational power.
