01 Jan 2018TL;DR: In this chapter an application of PCA, kernel PCA with their modified versions are discussed in the field of dimensionality reduction of hyperspectral images with their advantages and disadvantages.
Abstract: In this chapter an application of PCA, kernel PCA with their modified versions are discussed in the field of dimensionality reduction of hyperspectral images. Hyperspectral image cube is a set of images from hundreds of narrow and contiguous bands of electromagnetic spectrum from visible to near-infrared regions, which usually contains large amount of information to identify and distinguish spectrally unique materials. In hyperspectral image analysis, reducing the dimensionality is an important step where the aim is to discard the redundant bands and make it less time consuming for classification. Principal component analysis (PCA), and the modified version of PCA, i.e., segmented PCA are useful for reducing the dimensionality. A brief detail of these PCA based methods in the field of hyperspectral images with their advantages and disadvantages are discussed here. Also, dimensionality reduction using kernel PCA (one of the non linear PCA) and its modification i.e., clustering oriented kernel PCA in this field are elaborated in this chapter. Advantages and disadvantages of all these methods are experimentally evaluated over few hyperspectral data sets with different performance measures.

TL;DR: In this paper, the feasibility of vermicomposting of an invasive terrestrial weed Ageratum conyzoides for environment and economic benefits is discussed, which is based on biochemical characterization along with earthworm growth and cocoon production to evaluate the properties of the final product.
Abstract: This study illustrates the feasibility of vermicomposting of an invasive terrestrial weed Ageratum conyzoides for environment and economic benefits. This study presents the different mix proportion of substrate and cow dung as blending material in the vermicomposting process. It also advocates the potential of earthworm species Eisenia fetida for the bioconversion of A. conyzoides into a valuable end product. The work is based on biochemical characterization along with earthworm growth and cocoon production to evaluate the properties of the final product. The vermicompost obtained from all the reactors attained stabilization with increase in nutrients and decrease in total organic carbon (TOC), CO2 evolution rate after the end of the process. The pH was obtained in the range of 6.7–7.4 during vermicomposting. The final C/N ratio falls within 12–17 in all the reactors. The highest Total Kjeldahl Nitrogen (TKN) value observed in the final vermicompost was 2.67% which was higher than the initial value 1.83%. TOC decreased up to 30.05% at the end of the process. The earthworm biomass increased in a similar trend in all the reactors with highest biomass change of 25.75%. The results indicate that the biomass of A. conyzoides can be efficiently utilized to produce a mature vermicompost with the potential of further applications. It may be inferred from the findings that vermicomposting can be an alternative environment friendly option for the management of A. conyzoides and recommendable for on site management of the weed in an economical way.
