Besides, the proposed method is also designed to fit in the document layout analysis system.
Design rule checking, connectivity extraction and device extraction are important steps in layout analysis.
The second phase of the campaign [214] focused on three themes, document layout analysis, handwriting recognition and writer identification and a total of seven tasks.
In addition, some databases also support evaluation of tasks like document layout analysis, word spotting, writer demographics classification, writer identification and writer verification.
Textline detection is an essential step in many document processing tasks (e.g., layout analysis and optical character recognition), and numerous methods have been proposed for decades.
Jain et al. [9] presented a geometric layout analysis of technical journal pages using connected component extraction to efficiently implement page segmentation and region identification.
This modification of the usual workflow of historical document analysis eases the binarization task as well as other following tasks like layout analysis, line segmentation, OCR, etc.
One of the difficulties in the understanding of document images is document layout analysis, which is the first step in document image modeling.
The following processing steps of the system are described in detail: image preprocessing; layout analysis for the identification of the tables contained in the document; extraction and classification of the laboratory results.
The pages were scanned, and the complete database was annotated to support evaluation of tasks like document layout analysis [64, 65], mail classification [66], handwriting recognition [67 72] and writer recognition [38, 73].
