This is my code
wdenoise2(double(gr),3,'Wavelet','coif5','NoiseEstimate','LevelDependent','DenoisingMethod','Bayes','ThresholdRule','Median','NoiseDirection',["h","v","d"]);
and the image look like this. Can anyone help me to perform denoising images using wavelet s

imshow(denoised, [0 255])
assuming that the original image is uint8.
You should be considering using im2double() on your original image, processing the result. imwrite() and imshow() can accept the results directly, or you can im2uint8() after the processing.
