Hello,
I removed some noises from image and show the denoised image, I have used imwrite function to save the denoised image as follow:
.....
figure(2);clf;
imshow(a,[0 255]);
imwrite(a,'abc.png','png');
but the saved image is almost blank, a white background with few dot on it, any advise

Well, what is the value of a?
Is it a uint8? Or a double?

Maybe PNG doesn't like doubles. Try passing "a" into mat2gray()
before you save it with imwrite().
