Wavelet Image Denoising Based on The New Threshold Function
A new threshold function was proposed to overcome that hard threshold function is not continuous,soft threshold function has constant deviation and derivative discontinuity defects.It will be applied to using different thresholds denoising method with different decomposition level based on the D.J global threshold.Experimental results shows that the denoising result of new threshold function is superior to the traditional soft and hard threshold function in minimum mean square error (MSE) and peak signal to noise ratio (PSNR).
