Hyperspectral image processing is a field of investigation for electromagnetic spectrum to obtain spectrum for each pixel inside the image of a scene with the reason of locating, figuring out and detecting the overall analysis of the image. Anomaly detection makes use of such bands that incorporates precise traits carefully associated with goal gadgets. This paper affords a take a look at on the detection of anomalies for Hyper Spectral pictures based on nicely-designed dictionaries: heritage dictionary and capability abnormality lexicon. The detection method used is "Joint sparse representation" (JSR)-based dictionary selection. This paper approaches for the quantitative analysis of the receiver operating characteristics of the different Hyperspectral data sets. For the quantitative evaluation of this data via the implemented method with the various other methods, the ROC curves with point sensible self-assurance intervals had been plotted. Low Rank Sparse Representation method adorns an amazing overall performance at the AVIRIS-1, AVIRIS-2 and HYDICE sets giving a qualitative comparison of 95.25% Experimental analysis pointed out to the matter of fact that detecting anomalies based on potential abnormality and historical past lexicon production is capable of attain advanced consequences in comparison with different winning strategies.
