Image Processing - How can I create a 3D density plot based on the pixel intensity?

8 views (last 30 days)
Hello ppl,
I'm not a professional in Image Processing. But I'm looking a way of obtaining a 3D density plot that shows the areas with higher light intensity. I can load the image and even obtain the area values of areas in the picture below a certain threshold in the grey scale. Can any one help me of how I can tackle this?
