Abstract
Discussed herein are devices, systems, and methods for building mask generation. A method can include setting a respective pixel value of an image to a first specified value if the respective pixel corresponds, according to a three-dimensional (3D) point set, to an elevation greater than a specified Z threshold, otherwise setting the respective pixel value to a second, different specified value, grouping contiguous pixels set to the first specified value into one or more groups, determining a feature of each of the one or more groups, comparing the determined feature to a threshold and retaining the group if the feature is greater than a threshold, otherwise removing the group, and providing a building mask that includes pixels of the retained group set to a value and other pixels set to a different value.
