Leveling method for airborne electromagnetic data based on the curvelet transform and adaptive group-sparse variational model

Earth, Planets and Space
In airborne electromagnetic data processing, correcting leveling errors is critical for ensuring data accuracy. Traditional leveling methods predominantly rely on time-domain and frequency-domain analysis to characterize leveling errors.

Cosmological Non-Gaussian Signature Detection: Comparing Performance of Different Statistical Tests

EURASIP Journal on Advances in Signal Processing, 2005
Currently, it appears that the best method for non-Gaussianity detection in the cosmic microwave background (CMB) consists in calculating the kurtosis of the wavelet coefficients.

Adaptive filter and threshold for image denoising in new generation wavelet

Ho Chi Minh City Open University Journal of Science - Engineering and Technology, 2016
In reality, the nature images have the noise values because of many reasons. These values make the quality of images to decrease. Wavelet transform is proposed for denoising and it gives the better results.
