I have been working on a plugin (to be compile and run by imageJ) that asks the user to select two images, compares the images to make certain they have the same dimensions, and then calculates the relaxation parameter for each pixel. The relaxation parameters could be put into a third image that must have contrast and shown after the calculations finished. but the final image doesn’t look perfectly because the maximum possible range of 32-bit numbers is not relevant assume to my calculation for the final image (which is approximate 0-2300 millisecond).
