Based on wavelet threshold denoising method to add
no vote
To read the signals, then artificially added white noise and Wavelet threshold denoising method of additive white noise of ECG signal denoising, and the original, add white noise and noise to the image, and also calculate the signal to noise ratio, root mean square error.

Based on the top-hat transform under non-uniform i
no vote
Because some of the image is in the form of non-uniform illumination, so in order to make the image more clear, the images can be used in top hat transformation, the basic idea is to open the process of the image, and then make the image clearer.

Face recognition based on binary image method and
no vote
Face recognition methods is to first image binarization, and then through a series of actions, so as to outline the face area, but the basic method for certain image cannot be accurately sketched. Improvement of erosion and dilation are joined in these two steps, thus accurately sketched out the face area.

Reaching law of discrete-time sliding mode positio
no vote
Main features for uncertain objects, use the discrete sliding mode variable structure control theory to explore location tracking for uncertain objects. Rate of a discrete-time approach is designed sliding mode position tracking algorithm accessibility condition of sliding mode control is derived. The algorithm to discrete signal as input, design rate of a discrete exponential approach, according to the current state of the system, adjusted purposefully controllers, discrete Kalman filtering to interference and noise filtering. Simulation, this algorithm in the condition of no disturbance and no noise, accurate location tracking and disturbance and noise, is robust and anti-interference, and better meet the requirements of position tracking control. Note: Add without m Kalman filter is determined by the code value 1 or 2.
