 ### Description
 Paraphrasing the abstract of the original paper, _the document spectrum (or docstrum) is a method for structural page layout analysis based on bottom-up, nearest-neighbour clustering of page components. The method yields an accurate within-line, and between-line spacings and locates text lines and text blocks._
