Hi everyone, I have X-ray images of a porous solid object having internal pores (voids). I want to compute spatial and radial distribution of these internal pores (voids). Any suggestion how can I perform this using Image processing tool of MATLAB. Thanks in advance.

See my Image Segmentation Tutorial: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862 If you still have questions, post your image and your code. It's hard to give specific image processing advice without an image.

I have a stack of these 2D image slices representing one complete 3D solid object. In this figure white intensities are representing internal pores (voids) of solid object. I want to compute its radial distribution, internal pores (voids) intensities as a function of radial distance.

Just scan the image getting the radius for every voxel location, then increment your distribution by 1 for that distance
for col = 1 : columns
for row = 1 : rows
for slice = 1 : numSlices
radius = round(sqrt((row - yCenter)^2 + ........
radialDistribution(radius) = radialDistribution(radius) + 1;
end
end
end
