    • Image denoising based on dual-tree complex discrete wavelet transform 

      Hadeel Nasrat, Abdullah; Shaikh N. S., AB Rahman; A. N., Abdalla (Universiti Malaysia Pahang (UMP), 2009-06-20)
      Complex discrete wavelet transform (CDWT) has significant advantages over real wavelet transform for certain signal processing problems. In this paper, denoising of SAR images based on Complex discrete wavelet ...

    • LMMSE-based low complexity image denoising in non-uniform directional filter bank 

      Yahya Naji Saleh, Obad
      This dissertation is about creating a non-redundant, effective and low-complexity denoising method. Denoising an image involves removing noise from an image to keep the original elements of the image and remove unwanted ...

    • Wavelet based distortion measurement and enhancement of ECG signal 

      Md. Abdul, Awal; Mohiuddin, Ahmad, Prof. Dr. Engr.; Ismail, Daut, Prof. Dr.; Ernie, Che Mid; Mohd. Abdur, Rashid, Dr. (Institute of Electrical and Electronics Engineers (IEEE), 2012-02-27)
      This paper describes the research carried out to eliminate the noise found in ECG signal and cardiac rhythm using Coiflet wavelet since its scaling function is closely related to the shape of ECG and suited for denoising ...
