A novel scheme to the area measurement of multiple image objects is proposed. This scheme is suitable for the simultaneous and exact measurement of multiple objects’ areas with different shape. A geodesic active contour is applied and this scheme consists of two steps. Firstly
the active contour converges to the object’s contour edge from an initial position via the iteration of level set functional . Secondly
for the convergent active contour
a sub-pixel area measurement and counting the number of internal pixels of image objects are applied to compute every object’s area simultaneously. Experiments indicate this scheme’s measurement repetition error can decrease to 0.5%. Compared to conventional area measurement schemes
this scheme is highly efficient (i.e.
simultaneous measurement of multiple objects’ areas) and highly accurate.
