Abstract: This paper presents the evaluation of an image restoration approach based on a bilateral Gaussian filter (BGF) to address signal identification for spectrum sensing. The proposed methodology ...
Convert librosa python feature extraction code to MATLAB. Using the MATLAB feature extraction code, translate a Python speech command recognition system to a MATLAB system where Python is not required ...
It’s no secret that artists are known for incorporating hidden messages in their work, from The Beatles’ track ‘Lucy in the Sky with Diamonds’ spelling LSD to the backmasking of Missy Elliot’s "flip ...
For visualising signals into an image, we use a spectrogram that plots the time in the x-axis and frequency in the y-axis and, for more detailed information, amplitude in the z-axis. Also, it can be ...
Abstract: In this paper, we study American sign language (ASL) hand gesture recognition using Doppler radar. A set of ASL hand gesture motions are captured as micro- Doppler signals using a microwave ...
It probably can’t have taken long after the first spectrum waterfall display was created, before somebody had a go at creating a waveform that would create an image in the waterfall. We don’t know who ...
This article explains spectrogram of the speech signal (analysis and processing) with MATLAB to get its frequency-domain representation. In real life, we come across many signals that are variations ...
