Description: Based on the spectrum of the vuvuzela sound, this denoising technique simply computes an antenuation map in the time-frequency domain. Then, the audio signal is restored by computing the inverse STFT. See [1] or [2] for more detail about the algorithm.

Description: 利用Matlab软件平台对JTC进行了图像识别仿真实验，得到了二维及三维相关输出图像，显示出尖锐的相关峰。仿真实验表明：联合变换进行图像识别中存在强烈的零级干扰，干扰信号是有用信号的7.14倍，输出结果不理想；采用功率谱相减法可以消除零级强干扰，进而提高了图像的识别能力。-Simulations of joint transform correlator (JTC) using Matlab is implemented, and the 2-D and 3-D drawings of the correlation image are obtained. In the simulation experiments, the sharper correlation peaks are showed. The result shows that strong disturbance of zero rank exists in the simulation of JTC, and it is 7.14 times stronger than the useful signal thus, the power spectrum subtraction is used to eliminate the strong disturbance, and the capacity of image recognition is improved.

Description: 谱减算法为最早的语音降噪算法之一，它的提出，基于一个简单的原理：假设语音中的噪声只有加性噪声，只要将带噪语音谱减去噪声谱，就可以得到纯净语音幅度。这么做的前提是噪声信号是平稳的或者缓慢变化的-Spectral subtraction algorithm is one of the first voice noise reduction algorithm, which has been proposed, based on a simple principle: if only the voice of the noise additive noise, just noisy speech spectrum subtracting the noise spectrum, you can get clean speech amplitude . Do so on the premise that the noise signal is stationary or slowly varying Platform: |
