I was working on a research, I was having a noisy image and a clean image,
I proccessed a noisy image with two algo getting pimg1 and pimg2, I was confused how to make any one of it more like this clean image
I tried fft, imsharpen but nothing it look good
Clean image: image1

I processed the noisy image and got my image: pimg1

If this is the topic of your research then please post the answer when you complete your research. If you have a specific question about Mathworks software then please ask.

yes,sir,may be change the background color,and make the coin to white,such as
clc; clear all; close all;
im = imread('https://www.mathworks.com/matlabcentral/answers/uploaded_files/895635/image.png');
im = imresize(im,0.2,'bilinear');
im2 = rgb2gray(im);
bw = imbinarize(im2,'adaptive','ForegroundPolarity','dark','Sensitivity',0.45);
mk = bwareafilt(bw,1);
bw2 = imclearborder(bw);
bw2 = imfill(bw2, 'holes');
bw2 = bwareafilt(bw2,1);
bw2 = logical(bw2.*bw);
figure; imshow(bw2);
im3 = imadd(im2uint8(im2), im2uint8(bw2));
figure; imshow(im3);

"I was confused how to make any one of it more like this " <== Not sure I understand. Do you not know how to create a function that you can pass in different images to, and have it process them in the same way? If not, it probably goes over it in this:

Well I don't know what you're after. There are tons of filters to produce an infinite number of appearances. In addition, there are many, many denoising methods.
