i have a point cloud from an object i measured with a 3d microscope.
i am dealing with 3 vectors: x,y containing coordinate points in regular intervals and z containing the z-value (if there is no "Point, resp. no surface" the value is "NaN")
i would like to store and count "clusters" in 2D. By cluster i mean fibres. See pictures from scatter plot below:
how can i handle this? is it easier to convert the data to an image file and use matlabs morphological tools? i would be glad to avoid doing this.. thanks in advance
