Pixel-based classification methods, either supervised or unsupervised, are mostly used for land-cover and man-made structure detections. For the classical methods e.g. minimum distance, parallelepiped and maximum likelihood, detailed information can be found in (Lillesand and Kiefer, 1994).","Page language":"en","Page license":"CC-BY-SA-3.0","Page title":"Commercial softwares to extract features from aerial photos","Page views":"17","Page year":"Friday, 01-Jan-10 00:00:00 UTC","Modification date":"Thursday, 27-Nov-25 22:17:34 UTC"}
