Figure 4
Example of threshold mask. (a) Thickness image of the LiNixCoyAlzO2 particle. The arrows indicate the regions to be masked out. Specifically, arrow 1 and arrow 2 indicate the two small particles, and arrow 3 indicates the error part (a long stripe of yellow color) that comes from image alignment. (b) Mask generated from thickness image with a threshold set to 0.2. (c) Mask generated from `error' image [Fig. 2(d)] with a threshold set to 1. (d) Thickness image after applying the masks in (b) and (c). |
