Tryggo: Old norse for truth: The real truth about ground truth: New insights into the challenges of generating ground truth maps for WSI CAD algorithm evaluation

Tryggo: Old Norse for Truth Ground truth mapping has its origins in the computer science pattern recognition and machine vision fields and is a major activity associated with remote sensing (i.e. satellite images). Additionally, ground truth maps not infrequently find use in the following plurality of settings: motion video road detection and tracking, motion tasks, geoscience applications, sensor data and document analysis. Ground truth maps are needed to perform objective analysis and comparative evaluation of image analysis algorithms[1] and are “defined as a representation of the agreed correct result of the ideal layout analysis method (i.e., the result of the method that, if it existed, would put an end to the research problem).”[2] Operationally, such ground truth maps may be regarded as the “gold standard” by which results of other algorithms are compared.
