If the volume is too loud for a PA system, it will suffer howling problems which is caused by positive feedback sound. In current traditional howling sound suppressing projects, largely damage of the sound quality and operational difficulties of these issues have yet to be improved. Wavelet packet algorithm is used to suppress howling in this paper, it can evenly divide the audio signal band according...
A control system which can analog the external input and output characteristics of the diesel engine is aimed to be designed in this paper. Proposed a scheme that using the method named "Adaptive neural network based on model reference" to control asynchronous motor in order to simulate the external characteristics of the diesel engine. The simulation model of diesel engines, asynchronous...
The traditional Camshift tracking algorithm is easy to fall into local maximum when the target is occluded. It is easy to fail to track target when similar color interference or occlusion happens, and can't recover from failure. Aiming at this problem, the Kalman predictor and the inter-frame difference are adopted to improve Camshift algorithm. Firstly Kalman predictor predicts the next location...
