The NeighShrink, IAWDMBNC, and IIDMWT are some familiar methods for noise minimization from corrupted image. However, this mentioned method suffers from optimal recovery of the original image since the threshold value does not minimize the noisy wavelet coefficients across the image scale factor. In this paper, we propose an improved denoising method that provides an adaptive way of setting up minimum threshold by shrinking the wavelet coefficients so as to overcome the above problem using a new modified exponential function. The experimental analysis qualifying image such as Peak to Signal Noise ratio (PSNR) and Structural Similarity Index Measure (SSIM) are found better than the NeighShrink, IAWDMBNC, and IIDMWT methods. Moreover, our method retains the original image information with high visual quality
