Figure 2
Auto-edge counting method by the application of the Canny edge detection algorithm on a CBCT image. The three images are the porcelain fused metal crown phantom obtained without the metal artifact reduction option. (A) Baseline image, (B) edge binary image using the Canny edge detection algorithm, and (C) superimposition of the edge binary image and baseline image. Note that the edge binary image well described the edge of the object in the baseline image.
