Fig. 3 . The procedure of the three-dimensional (3D) image reconstruction by the stereo matching method on the basis of the coarse-to-fine method in this study (the template matching and the filtering were made from the image with the lowest resolution obtained after Down Sampling 3 to the original image (Template Matching 4), as indicated by the numbers from x to ).
