The second limit for valid points is that 0 b ! 1, which ensures that the point of intersection is within the line segment formed by the two consecutive edge points. In order to obtain reasonable measurements of LER and LWR, the blocky structures of binary lines and skeletons need to be smoothed. The smoothing process, which we have utilized here, involves 4 stages:Fig 11.

The labels 1, two, 3, and four mark the line topic to each and every of your four stages of smoothing described. All photos using the cyan-to-red colour scheme show the relative width on the opposite side in the line, in the skeleton centre, towards the edge; if a side is wider in proportion it is actually shown in red; narrower is shown in cyan., with parameterization as scalable, intersecting vectors. doi:10.1371/journal.pone.0133088.gnarrower, nevertheless, the influence of pixel position can commence to slightly raise the measured LER, up to 0.5 nm in our prior operate working with higher resolution (ca. one hundred,000x) BCP patterns. We mitigate this, in aspect, by smoothing each the centre line with the skeleton plus the outer edge, whilst constraining the positions with the edge points. Edge-to-skeleton distances are determined for all points around the smoothed line edge, matching together with the nearest points (shown in Fig 10A) around the smoothed skeleton line title= jrsm.2011.110120 which satisfy: edge ?xskel ??slopeskel edge ?yskel ??0 ??As derived in the dot solution from the vector around the edge-to-skeleton distance and also the orthogonal vector (1, slope) from the skeleton at that point, an interpolated point around the skeleton is often obtained (shown in Fig 10B). Line-width measurements can be created in conjunction with edge-to-skeleton measurements by acquiring a line segment on the opposing edge, title= a0023499 which is intersected by the vector created involving the edge point and skeleton point on the earlier step (shown in Fig 10C). The solution exists at a point on the line segment formed by the vector among the edge (xedge, yedge) and the skeleton (xskel, yskel) is scaled by a aspect, a, and on the line segment formed by the vector among two consecutive points around the transverse edge (xtrans1, ytrans1) (xtrans2, ytrans2), scaled by a factor, b (shown in Fig 10D). Offered that the two vectors are usually not parallel, thePLOS A single | DOI:10.1371/journal.pone.0133088 July 24,16 /Automated Analysis of Block Copolymer Thin Film Nanopatternsequations[77] for the scalars, a and b, are: d ? trans2 ?xtrans1 yskel ?yedge ?? skel ?xedge ytrans2 ?ytrans1 ?a ?d ? xedge ?xtrans1 ytrans2 ?ytrans1 ?? edge ?ytrans1 xtrans2 ?xtrans1 b ?d ? xedge ?xtrans1 yskel ?yedge ?? edge ?ytrans1 xskel ?xedge  ?0??1??2?An intersection is considered valid when 1
