Changing color using the mouse
显示 更早的评论
Dear all, From a SEM picture of nanoparticles, I have to digitalize it, then changing the color of the particles by clicking on them and make the FFT. As far as now, I can digitalize and make the FFT, but I have not found how to change the color of the particle by clicking on them. I have used the edge function to detect the edges of the particles to try to do like in paint with the Fill with color function but now I am stuck. Do anyone have an idea how I could proceed ? The only function I have found in Matlab is ginput but it seems only to take data from the figure and not apply changes to them.
