“…2) Data Transformation: Data transformation plays an important role in the proposed ensemble classifier. In this article, minimum noise fraction (MNF) [31] is used as the transformation technique. MNF chooses new components to maximize the signal-to-noise ratio.…”

“…Here we compare the classification performance of several state of art with respect to our proposed model. In this section, a proposed preprocessing MBF-Algorithm will compare with some existing popular feature extraction methods such as MNF [10], PCA [11], SPP [12], LPP [13], MSME [14], and SPA [15]. The kappa coefficient of classification (Kappa) and overall accuracy (OA) has used to show the accuracy after classification.…”

“…A Hughes effect [7], is related to low generalization ability of the "classifier", which frequently has encountered in several "pattern recognition" applications such as; object recognition, text categorization, computer vision and gene expression data [8], [9]. There are several feature techniques such as "MNF" (minimum-noise fraction [10]), "PCA" (principal component analysis [11]), "SPP" (sparsity preserving projection [12]), "LPP" (local preserving projection [13]), "MSME" (multi-structure manifold embedding [14]), and "SPA" (sparsity preserving analysis [15]), etc. Though the some important information at feature approach has not obtained properly, therefore it causes the performance degradation in HSI classification.…”

“…MNF transforms were used to separate noisy data and to reduce data dimensionality and the workload of subsequent processing. The correlations between any two bands were eliminated after MNF transformation, and noise was reduced [39]. Before MNF was applied, the Landsat OLI 30 m spatial resolution multispectral bands were fused with the 15 m panchromatic band, using the Gram-Schmidt (GS) fusion method.…”
