This method … WebJul 29, 2024 · A new definition of ‘spectral contrast angle (SCA)’ based on ‘distance correlation’ is proposed and noted to be more sensitive to the change in spectral shape as …
WebDetails For each pixel the spectral angle mapper calculates the angle between the vector defined by the pixel values and each endmember vector. The result of this is one raster layer for each endmember containing the spectral angle. The smaller the spectral angle the more similar a pixel is to a given endmember class. WebSkyline can calculate following measures of spectral similarity: between the transition peak areas and library spectra (dotp); ... most recent versions actually use normalized spectral contrast angle. Since dot products are calculated using the peak areas they are graphically represented in the Peak Area Replicate Comparison plot. They are also ...
