Flow chart of image registration technique in the CAM-VMI. A The copied product (solid-gray pattern) superimposed onto the template (dashed-black square), B The two images superimposed after optimal resizing, rotation, and repositioning, C Error reflects the constructional accuracy by comparing the template (dashed-black square) and the best-fit (solid-black pattern), and D Effort reflects the required adjustment by comparing the best-fit (solid-black pattern) and the original copied product (solid-gray pattern)
