Audio-Only Speaker Identification using Principal Component Analysis based Back-Propagation Learning Neural Network in Noisy Environment
Abstract: This paper introduces text dependent speaker identification system on Principal Component Analysis based Back-Propagation learning neural network which deals with detecting a particular speaker from a known populations under noisy environment. For audio pre-processing, ends point detection, silence parts removal, frame segmentation and windowing techniques have been used and wiener filter has been applied to remove the background noise from the audio speech utterances. To reduce the dimension of the …

BIS Processes in the Human Neural Networks and Asymptotic Periodic Solutions of the Evolution Equations in the Brain Nanosystem using Jacobi Elliptic Function
Abstract: Our perseverance is dependent upon the normal functioning and fluctuation of the brain. That functioning involves complex electrical activities. These in turn generate subtle waves which were first noticed and studied by Hans Berger. These are essentially electrical rhythms in the brain which, when recorded by means of instruments called electroencephalograms or EEG on a roll of paper, appear as complex wave forms. In this paper, based on Jacobi elliptic …

Noise-Removal Techniques for ECG Signals – A Survey Approach
Abstract: Modernization in medical sciences has led to the electrical signals vary according to the variation in the biological activities and abnormalities in the human body. ECG measures and records the electrical activity of the heart. Hence, the signals should be free from undesired signals to accurately analyze the abnormalities in the human body. Different techniques have been applied to make the ECG signal noise free. This paper presents a survey …

Simulation of Complex Camera Motion Paths for Image Stabilization
Abstract: Image stabilization (IS) is a family of techniques used to reduce blurring like effects associated with the motion of a camera during exposure. Specifically, it compensates for pan and tilt (angular movement, equivalent to yaw and pitch) of a camera. These camera motions are combinations of basic movements like linear horizontal or vertical motions, circular motion or sometimes arbitrary motions. In true sense motion blur generated by these motions is …
