v1 v2 11 11 reconstruction, indeed for any systematic computer processing. 12 12 13 === Non-interactive error correction === 14 13 15 The vector parser tries to automatically deal with troublesome 14 16 situations. However, if it is unable to correct a problem … … 19 21 contour slides. Below we discuss common inconveniences and our 20 22 strategies for fixing them. 23 24 === Leaking structures === 21 25 22 26 The most common defect is gaps in structure outlines. It frequently … … 29 33 the spot indicated by a red arrow on Fig.~3A)'''. 30 34 35 === Gap filling algorithm === 36 31 37 It is handled by a heuristic gap filling algorithm ([wiki:barSoftwareGapFillDetails detailed description]). The main idea 32 38 behind this algorithm is to expand the contours by applying a [http://en.wikipedia.org/wiki/Mathematical_morphology dilation] filter ([http://www.imageprocessingplace.com/DIP-3E/dip3e_main_page.htm Gonzalez2008]) until the boundary closes. If a very … … 36 42 reconstructed structures were adequate and the gains in time were 37 43 tremendous as compared with manual cleaning. 44 45 === Duplicated labels within a single contour === 38 46 39 47 Another common difficulty is an absence of borders drawn within an outline containing multiple labels. … … 49 57 and correct it. 50 58 59 === Labels placed over contours === 60 51 61 Error correction procedure also looks for labels anchored directly 52 62 above contours which may happen when a structure is defined as a thin … … 58 68 as the whole procedure works non-interactively. 59 69 70 === Unlabelled area === 71 60 72 Another problem we encountered during tracing was the lack of labels 61 73 attributed to some areas. 3dBAR vector parser automatically detects
