- W2182330979 abstract "In this paper classification performance of Hyperspectral images using two different data decorrelating transforms is investigated. The tradeoff between the discrete wavelet transform (DWT) and the principal component analysis (PCA) is measured using different compression algorithms found in the JPEG2000 standard. These cross-component transforms can be evaluated in order to obtain a comparison of how well each transform can decorrelate data, reorder data optimally, speed of implementation, and effect on mineral classification performance. In addition, two scalability options defined by JPEG2000 were used: color and quality. Compression algorithms were carried out for the DWT and the PCA using the same set of parameters; the same Hyperspectral image, the same classification algorithm—spectral angle mapper (SAM), and the same type of compression: lossless compression. The purpose of this comparison is to be able to determine how much partial decompression is needed in order to achieve a 90% hit rate when classifying several minerals. This evaluation is focused primarily on two types of Mica called Aluminumrich and Aluminum-poor Mica. Our past research using PCA has shown extremely good overall classification performance. However, this transform has the disadvantage of higher computational complexity. This prompted us to try out an alternate lower complexity transform such as the DWT. The classification results were found poor as compared to PCA. The complex nature of our classification does not allow us come to a complete judgment of this finding. Thus, other data sets involving low complex nature of classification shall be dealt in our future work. The simulation results conclude that the DWT is seven times faster than PCA and allows parallel processing huge data sets." @default.
