AUTOMATED PRINTED CIRCUIT BOARD (PCB) DEFECT DETECTION USING DIGITAL IMAGE PROCESSING TECHNIQUE
Abstract: This work presents a Digital Image Processing (DIP) solution involving the use of image filters and processing functions to analyse the reference and the test images of a Printed Circuit Board (PCB) to yield a resulting image in which open and short circuits have been highlighted. The problem solved was the dependence of other PCB defects detection methods on the absence of deformation in the test image and this was …

Reduction of Ocular Artifacts in Single Channel EEG by EEMD-IMF Thresholding
Abstract: AbstractElectroencephalogram (EEG) is a widely used signal for analyzing the activities of the brain and usually contaminated with artifacts due to the movements of eye, heart, muscles and power line interference. Among these ocular activities creates significant artifacts and makes the analysis difficult. In this paper, ensemble empirical mode decomposition (EEMD) inspired by wavelet thresholding is used for the correction of ocular artifacts (OA) in EEG signals. Unlike the conventional …
