Analytic Subbing On Application Based Denoising Techniques Using Wavelet Transform

Data pre-processing is challenging as it involves extensive manual effort and time, includes the process of noise removal referred as signal denoising or simply denoising. Noises present in signals are difficult to recover using the traditional methods. Now Wavelet Transform is used for denoising techniques. The implementation results reveal that the proposed technique achieves a state-of-the-a...

Sensorless Speed Measurement of AC Machines Using Analytic Wavelet Transform

A new method for sensorless speed estimation of ac machines, using the analytic wavelet transform of the stator current signal, is proposed for a direct torque control drive. A comparison with results obtained using the short-time Fourier transform is included. The proposed method can be implemented in real time on a digital signal processor. The time–frequency resolution obtained and the compu...

Frequency Estimation Using Analytic Signal via Wavelet Transform

Frequency estimation of a sinusoid in white noise using maximum entropy power spectral estimation has been shown to be very sensitive to initial sinusoidal phase. This paper presents use of wavelet transform to find an analytic signal for frequency estimation using maximum entropy method (MEM) and compared the results with frequency estimation using analytic signal by Hilbert transform method a...

Breast abnormalities segmentation using the wavelet transform coefficients aggregation

Introduction: Breast cancer is the most common cancer among women in the world. The automatic detection of masses in digital mammograms is a challenging task and a major step in the development of breast cancer CAD systems. In this study, we introduce a new method for automatic detection of suspicious mass candidate (SMC) regions in a mammogram. Methods: Mammography is widely used for the early...
