Data processing and management is common now a days. In this paper, automatic processing of forms written in Kannada language is considered. A suitable pre-processing technique is presented for extracting handwritten characters. Principal Component Analysis (PCA) and Histogram of oriented Gradients (HoG) are used for feature extraction. These features are fed to multilayer feed forward back pro...

A particularly challenging context for dimensionality reduction is multivariate circular data, that is, data supported on a torus. Such kind of appears, example, in the analysis various phenomena environmental sciences and astronomy, as well molecular structures. This article introduces Scaled Torus Principal Component Analysis (ST-PCA), novel approach to perform with toroidal data. ST-PCA find...
