Supervised classification (cont.)
{"Image DocumentName": "Supervised classification (cont.)", "Image ImageDescription": "Classification stage. Fig Pixel observations from selected training sites plotted on scatter diagram. Use two bands for demonstration, can be applied to any band number. Clouds of points \uf0ae multidimensional descriptions of the spectral response patterns of each category of cover type to be interpreted. Minimum-Distance-to-Mean classifier. Fig Mean vector for each category. Pt 1 \uf0ae Corn. Pt 2 \uf0ae Sand ?!! Advantage: mathematically simple and computationally efficient. Disadvantage: insensitive to different degrees of variance in the spectral response data. Not widely used if the spectral classes are close to one another in the measurement space and have high variance.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
