So in that case, how to interact with pixels from QtQuick2. Lets say I want to get value of the pixel on the image that user click on.

You can't. If you want to work on pixels, fall back to Qt/C++.

Maybe you could calculate the position of the x, y of mouse from qml
then use Qt/c++ to load the image and print out the value according to the x, y position
