  2. IMAGE PROCESSING PIPELINEand supporting tools Image Acquisition If required, web-based imagery is downloaded Resampler 256x256 tiles are resampled into desired dimensions and resolution Training Training image tiles are generated from user labels (supervised) or a uniformly random distribution Feature Extraction If required, texture and shape metric features are generated UNSUPERVISED Labeling User-sampled points are assigned to user-defined classes SMOOTHING / SUPER RESOLUTION For classification images that already exist, these images can be fed directly into theenergy minimization to benefit from smoothingor to be reformulated at a higher spatial resolution SUPERVISED Variances Update Class-conditioned Variances MRF Energy Minimization Means Update Class-conditioned Means FUTHER ITERATION REQUIRED SceneAnnotator WebImageDownloader MRFLandClassifer
