Denoising with real and complex wavelets
We present the comparison between Daubechies complex-valued wavelets (DCW) and Daubechies real-valued wavelets (DRW) in denoising application. The discrete dyadic wavelet transform (DWT) with decimation (n...

Near infrared face recognition by combining Zernike moments and undecimated discrete wavelet transform
This study proposes a novel near infrared face recognition algorithm based on a combination of both local and global features. In this method local features are extracted from partitioned images by means of undecimated discrete ...
