How to improve my image quality with using specific image filtering?

I want to improve my image quality but I don't know what filter or tool that help me to do that with a RGB image I try Gaussian but it's not enough I want more improvement in my picture:

code:

I=imread('82.jpg');
figure
imshow(I)
Gauss = imgaussfilt(I,1);
figure,imshow(Gauss)

Well of course a filter to blur the image won't improve it - not sure why you thought it would. The things you need to improve it are optical, not software. These are:

1. Use a faster frame rate to reduce motion blur.
2. White balance your camera to improve color fidelity.
3. Use a smaller aperture (larger F/stop) to improve the depth of field.
4. Use more light to reduce noise and improve colors.
5. Use a better camera for obvious reasons.
6. Use a better lens to reduce optical aberrations (spherical, distortion, coma, chromatic, etc.)
7. Use better lighting, perhaps softboxes or umbrellas

Following my suggestions above will give you a better image than you can get with post processing a crummy image in MATLAB.

thank you for your answer but I have a project and my instructor want to me to take a picture with low quality and from my laptop cam but insist to use matlab filter to make the picture better but I don't found anything to make it better

Try using imadjust() to increase the contrast. You can also use imfilter() or conv2() to sharpen the edges with the kernel he probably gave you in class.
