Fig. 5From: Image processing for optical mappingGrouping. a Segments a and c are grouped as this grouping provides the best continuity in terms of adhering to the constraints of spatial proximity and orientation similarity. The grouping (a,b) satisfies the spatial proximity constraint but in terms of orientation similarity, it is less optimal that the grouping (a,c). The grouping (a,d) is invalid as we require the segment d to be strictly non-overlapping with segment a. b, c Two examples of accurate grouping in the presence of distractors. The adjacent fragments are colored differently to aid visualizationBack to article page
