Image denoising based on quaternion wavelet Q-HMT model

Based on the algorithm of wavelet domain HMT model, the image achieved often has ringing distortion in the edge. This paper puts forward a model based on quaternion wavelet Q-HMT model. Combining the quaternion wavelet transform model with the traditional HMT model, the new algorithm has the advantage of good translation without deformation and the advantage of the rich phase. The experimental results show that this algorithm is superior to the traditional algorithm of denoising in peak signal-to-noise ratio and image effect is more superior to the traditional denoising algorithm.
