If I1 ans I2 are my two images Then I want to plot I1(i,j) against I2(i,j) for all the pixels

you can try module plot in opencv_contrib

what do you mean for plot I1(i,j) against I2(i,j) Are you looking for a 3D plot with 2 dataset ? Maybe the difference image I3 = I1 - I2 might be a simple solution. In this case take care to sign... I1,I2 I3 should be 16bit signed to avoid to collapse all <0 to 0 due to saturation.
