Zonal OCR extracts only specified data fields from scanned documents and stores them in a structured database for further processing. It preferentially extracts important data unlike regular OCR, which extracts all data indiscriminately. Zonal OCR allows relevant data capture from documents with minimal human intervention, avoids redundancy, and enables easy team access to save time over manual data entry. However, it may fail to extract data from semi-structured or complex multi-line documents. Common applications of zonal OCR include invoice, purchase order, and ID card digitization.

Offline Omni Font Arabic Optical Text Recognition System using Prolog Classif...GBM
This thesis proposes a complete system that classifies and recognizes machine-printed
Arabic text. The input to the system is a clean, high-resolution Tag Image File Format
(.TIFF) that contains Arabic text to be recognized; the output is simply the generated
Arabic text saved in a Microsoft Word Document (.DOC) file of the recognized Arabic
text. The technique is based on cleverly describing the text in terms of shape primitives
derived from Freeman chain codes. A rule-based data enhancement technique is used
to improve recognized features as much as possible. The recognized features are
processed by a Prolog feature-matching engine to classify character classes as well as
diacritic information as three separate streams (character class stream, diacritic stream
and corners information stream). In addition to the three provided streams, estimated
font size is also provided as a fourth input. Characters are finally determined by
processing a permutation of the three streams using Definite Clause Grammar (DCG).

Extract and Analyze Data from PDF File and Web : A ReviewIRJET Journal
The document describes a proposed system to automate the analysis of student exam results that are typically provided as PDF files. The system would extract key data from the PDFs using PDFBox and store it in a database. It would then generate various reports like department topper lists automatically using queries on the stored data. This would make the exam result analysis process more efficient by reducing manual work and errors compared to current methods where data is copied from PDFs into excel manually. The proposed system aims to overcome limitations of existing semi-automated systems by allowing full automation of result extraction and analysis with features like interactive GUI, SMS/email notifications, and graphical result visualization.

Problem with Converting PDFs to Excel
PDFs are usually one of the most readable formats for viewing data but converting them to Excel sheets
is a hard because:
1. We need a format with simple primitives and no structured information
2. There's no equivalent of a table component in PDF files as tables are created with straight lines and
coloured backgrounds
3. As tables in PDFs are drawn like images, detecting or extracting a table is a complex process
4. PDFs created by digital image or by scanning a printed file have distorted lines and no textual
elements
3. 3
How does Exporting Scanned PDF to Excel
Work?
1. PDF to Word/Excel/Direct Text converters are used to copy the information
2. OCR (Optical Character Recognition) engine is used to read the PDF and then to copy its contents in
a different format like simple text
3. Additional programming like PDFMiner (Python-based) or TIka (Java-based) is required to process
the text into the required format or store them in tabular format
4. Code snippets written to push formatted data to Excel or configure online APIs if it’s Google Sheets
4. 4
Methods to Detect Tables in Textual PDFs
Detecting Tables Using Stream: This technique is used to parse tables that have whitespaces between
cells to simulate a table structure. Basically, identifying the place where the text isn't present.
Detecting Tables Using Lattice: Compared to the stream technique, Lattice is more deterministic in
nature. It first parses through tables that have defined lines between cells. It can automatically parse
multiple tables present on a page.
5. 5
Identifying Tables with Python and
Computer Vision
Computer Vision can help us find the borders, edges, and cells to identify tables.
1. The first step is to convert the PDF into images because CV algorithms are implemented on images
2. Inverse image thresholding and dilation technique can enhance the data in the given image to obtain
the image contours
3. Iterate over the contours list to plot the output using matplotlib
6. 6
Identifying Tables with Deep Learning
Data Collection: Deep-learning based approaches are data-intensive and require large volumes of
training data for learning effective representations.
Data Preprocessing: This step is the most common thing for any machine learning or data-science
based problem. It mainly involves understanding the type of document we're working on.
Table Row-Column Annotations: After processing the documents, we'll have to generate annotations
for all the pages in the document. These annotations are basically masks for table and column.
Building a Model: The Model is the heart of the deep learning algorithm. It essentially involves designing
and implementing a neural network. Usually, for datasets containing scanned copies, Convolutional
Neural Networks are widely employed.

Business Benefits of Automating the PDF to
Excel Process
1. Reduces the time needed to search and copy/paste the required information manually
2. Reduces the probability of typos and other errors during manual extraction
3. By automating the PDFs to Excel conversion, we can easily integrate your data with any third-party
software
4. Business efficiency can be improved by automating the entire extraction pipeline and running it on a
batch of PDF files to get all desired information in one go
