A Novel Dual Tree Complex Wavelet Transform Based Ultrasound

Various noises present in the ultrasound images are the main hindrance of accurate detection and diagnose of the disease. These noise degrades the quality of the ultrasound image to that extent that it become impossible for the expert to deduce some conclusion out of this. In this paper, A dual tree complex based DWT is used for de-noising ultrasound image. Comparison with the existing technique with the help of simulation program designed for this very purpose reveals that the proposed method is able to remove the noise better than the existing technique.
