GeoImage Workflow Editing Resources: GIWER

Abstract

While various open-source and commercial image-processing software exist, and they have high-level image-processing skills, there is no flexibility to assemble custom workflows where the experience of the evaluator can be built into the system. Therefore we have developed the Giwer (acronym for GeoImage Workflow Editing Resources, pronounce gaiver) open-source software package for handling, processing and analyzing drone images with the possibility of flexible workflow creation. Giwer has many image-processing functions that can handle traditional RGB, greyscale and hyperspectral images and apply them for their interpretation for any number of images. Giwer has further useful capabilities to organize images and their metadata (EXIF) into a database to navigate thousands of images. Users can compile their own workflows based on the available image-processing functions. Thus the created workflow involves users’ knowledge and experiences. The workflows process any number of images at once. This approach can accelerate the performance if you have a working algorithm group.
