WitrynaIn analytical chemistry, spectral imaging of complex analytical systems is commonly performed. A major task in spectral imaging analysis is to extract signals related to important analytes present in the imaged scene. Hence, the ﬁrst task of spectral image analysis is to perform an image segmentation to extract the relevant signals to analyze. Witryna7 mar 2012 · It sounds like you might need some sort of 3D scatterplot. If you have 20 images that are 256x256, how I imagine this working is, Take your 2D FFT or 2D DCT (or blockwise FFT/DCT) for each image. Normalize all the values so you can have a good comparison between each image. Concatenate all the frequency domain …
