Journal ArticleDOI
Performance Study of Different Denoising Methods for ECG Signals
TL;DR: Five common and important denoising methods are presented and applied on real ECG signals contaminated with different levels of noise, including discrete wavelet transform, adaptive filters, LMS and RLS, and Savitzky-Golay filtering.
Journal ArticleDOI
Drowsy Driving Detection by EEG Analysis Using Wavelet Transform and K-means Clustering☆
Nikita Gurudath,H. Bryan Riley +1 more
TL;DR: This research aims to develop a driver drowsiness monitoring system by analyzing the electroencephalographic (EEG) signals in a software scripted environment and using a driving simulator, and unsupervised learning through K-means clustering is employed.
Journal ArticleDOI
Robust Lane Detection in Shadows and Low Illumination Conditions using Local Gradient Features
TL;DR: The contribution of this paper is the use of vertical gradient image without converting into binary image, and introduction of characteristic lane gradient spectrum within the local window to locate the preciselane marking points along the horizontal scan line over the image.
Proceedings ArticleDOI
Machine learning identification of diabetic retinopathy from fundus images
TL;DR: The experimental results indicate that this method can produce a 97.2% and 98.1% classification accuracy using ANN and SVM respectively invariant of rotation, translation and scaling in input retinal images as opposed to a fixed mask based on the matched filter method.
Proceedings ArticleDOI
Short range forest channel modeling in the 5 GHz band
TL;DR: In this paper, the authors presented a wireless channel characterization for a short-range, temperate, medium density forest environment, at a center frequency of 5.12 GHz with a 50MHz bandwidth signal and obtained impulse response estimates.
