In analogy to the human mind, image understanding is the computational process of extracting information from images, i.e. locating, characterizing, and recognizing objects and other features in the scene. In Earth observation, image understanding refers to the tasks and methods that take pre-processed and assimilated images as an input and extract information from them. For example, a human task would be visual image interpretation by delineating objects in an image scene. However, image understanding is a cyclic process and already happens during pre-processing and assimilation. For example, the cloud mask for EO images is a product of image understanding, namely of classification, that is available very early in the image processing chain prior to many pre-processing tasks.
Explain why image understanding has to be considered as a cyclic process
