Welcome Kumar, I wish I could help you, but it's probrabaly because it's getting late here, but I'm confused about your post. What is it basically that you want to know? Those 4 different images confuse me too. Do you have any before/after images instead?

Guassian he wants his image look sharper and brighter.His problem is when he edit>transform the picture, it look blur and losts image quality(he uses very small picture source image).

He want you to teach him how to correct his images without loosing the image quality that's it.

The rest of also carries the same about the poor image quality..

Thanks MIndBlasting, but I don't think he's interested anymore; he asked that question 3 weeks ago.
