Video Noise Analysis Using Frequency Domain Algorithm
摘要
In the recent years, the technology has upgraded very fast. Videos and images have become part of life. Video Data generated is very large and can be used for analysis in real time. Nowadays surveillance system is installed in the local building and society. This paper addresses the problem of video noise analysis and noise detection. The method in this paper takes video as a dataset. It uses Short-time Fourier transformation and Sparse Fourier parse transformation as frequency domain algorithm on the audio to get a spectrogram. It can used to analyze the noise pattern in the spectrogram. As the surveillance system can be used thief alert function. It can also help us against fire issues and alert the nearby fire-fighters.
