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?

I'm not clear - is this a 3D volumetric image, like from CT or MRI, or is it a 2D image?

This sounds like surf(rgb2gray(YourImage))

I would recommend using mesh() since the number of data points in many images makes a surf plot look like a black spiny blob.

surf(rgb2gray(YourImage),'EdgeColor','none')
