LAKSHMI Posted January 28, 2015 Report Share Posted January 28, 2015 I am doing my masters in geoinformatics. My thesis topic is MODELING OF SPATIAL OBJECTS FOR LAND COVER CLASSIFICATION USING FUZZY TOPOLOGY. I need to calculate a measure of the distance of a pixel from its mean pixel. for that I need to calculate (x-m)T* (cov©)-1 * (x-m) where x- pixel vector m-mean vector of the sample (signeture for supervised classification T-transpose function cov©-covariance matrix of the sample I have a raster image from which x can be taken, mean and covariance matrices. I made a model to calculate (x-m) and got a result as a raster image. can anyone help me to proceed further ? Quote Link to comment Share on other sites More sharing options...
3dbu Posted January 28, 2015 Report Share Posted January 28, 2015 pls share a clip of our raster or image for make many test and then give the right form to procedure in your calculate, regards. Quote Link to comment Share on other sites More sharing options...
