In one exemplary embodiment of the present invention, a method of
detecting a desired object at a candidate pixel from an image is
provided. The method includes the steps of (a) selecting a representative
point in the desired object; (b) determining first representative
cross-sections of the desired object by passing first lower dimension
planes through the representative point; (c) passing at least one second
lower dimension plane through the candidate pixel; (d) using region
segmentation to separate the candidate pixel containing second regions
from the rest of the pixels in each of the at least one second lower
dimension plane; (e) matching at least one of the second regions with at
least one of the first cross-sections; (f) determining a match value
based on the result of step (e); and (g) using the match value to
determine if the desired object is detected at the candidate pixel.
